WARNING
Types of sample uids and cleaning uids
The unit is designed for measuring the particle number concentration in
liquid. The particle count is determined for various sizes.
Never use the unit with the liquid types listed below, to prevent false mea-
surement and the possibility of accidents and damage to the unit.
- Explosive liquid or mixtures containing explosive uid
- Liquid with a temperature of less than +15°C or more than +35°C
- Liquid with a pressure of more than 300 kPa (gauge pressure)
When using different types of sample uid where mixing can lead to reactions
such as thermal build-up, hardening, or particle generation, always perform
thorough cleaning to ensure complete replacement.

v
WARNING
Sample uid danger prevention
When toxic sample uid comes into contact with any part of the human body
or when toxic gases generated by the sample uid are breathed, there is a
danger of severe injury or death.
When sample uid comes into contact with other objects in the vicinity, there
is a risk of re, explosion, corrosion, deformation or other effects. Observe the
following points closely to prevent leakage and adherence of sample uid.
• In case of accidental contact with any potentially harmful uid, immediately
wash the affected part with plenty of water and contact a physician.
•Do not pass sample uids which can cause corrosion of uid-contacting
parts (PFA and sapphire) through the system.
•Observe the following points when setting up or dismantling a measure-
ment system.
- Check for any possible risks or toxicity of the intended sample uid.
- Take any required steps to prevent sample uid leaks, spray, or ex-
posure of the body to sample uid.
- Always use protective measures such as wearing dual gloves when
connecting or disconnecting tubes and connectors. Dispose of gloves
which have come into contact with uid in such a way that the gloves
do not come into contact with persons or equipment.
- Do not exert strong force or bending stress on tube joints to prevent
leaks.
- As far as possible, tubes and other piping parts should be built up as
a xed installation.
- Do not start to pass sample uid through the system before all con-
nections have been checked.
- This unit incorporates a leak sensor or other safety device, but to
verify safety you should always perform a thorough leak check before
starting operation. To ensure that the leak sensor operates properly,
the unit must be placed on a horizontal surface (inclination within 2
degrees; see page 2).

vi
•The pressure of sample uid passed through the unit may not exceed 300 kPa
(gauge pressure). Ensure that the supply system (sampler, sample uid lines
etc.) has sufcient pressure resistance.
•When using sample uid which may generate harmful gases, provide
adequate ventilation as prescribed by applicable laws and regulations.
• Before and after measurement, clean the entire sample uid system
thoroughly to remove any remnants. Otherwise unwanted effects such as
thermal build-up, hardening, particle accumulation etc. can occur. This is
especially important to prevent the possibility of serious accidents when
using the unit to measure different types of sample uids.
• After use, perform purging while observing any precautions regarding
the mixing of uids. As the last step, purge with pure water and verify
neutrality (pH7). Then ll the unit with ethyl alcohol and seal it.
• Dispose of waste sample uid only as prescribed by applicable laws and
regulations.
• Never mix waste sample uid with other substances unless absolute safety
has been established.
• Always follow the sequence: purging, measurement, exchange, measure-
ment
When using uids of different properties, always thoroughly purge
the uid system, and verify complete exchange before starting the
next measurement. This is to prevent unwanted effects such as sudden
thermal build-up, hardening, particle accumulation etc. that can be
caused by mixing. If this precaution is not properly observed, there
is a risk of a serious accident.

vii
• Pay attention to measurement, exchange, purging sequence
Some uids may be subject to emulsication, temperature rise, or other
effects when mixed with water. In some combinations, hardening or
precipitation may also occur. Before introducing sample uid, make
sure that there is no possibility of a chemical reaction.
Some possibly hazardous combinations and their effects are listed
below. (This list is not comprehensive. There may be other hazardous
combinations as well.)
• Water and sulfuric acid
A high-temperature reaction will occur.
• Oxidizing substances and reducing substances
Example: nitric acid and isopropyl alcohol
A violent reaction (explosion etc.) will occur.
• Acidic and alkaline substances
Example: introducing ammonia water after nitric acid is pro-
hibited
Damage and stress due to neutralization heat and reaction
heat may occur.
Always purge with pure water in between.
• Water and oil, water and organic solvent, or oil and organic
solvent
Emulsication may occur.
Purge with plenty of ethyl alcohol (followed by n-hexane
if required).

Precautions
• Operate the unit only as described in this manual.
• The uid-contacting parts of this product are made of sapphire and PFA,
which provides high resistance against corrosion by hydrouoric acid.
However, gradual corrosion may occur in some cases. If hydrouoric acid
was left in the unit for a long time, replacement of uid-contacting parts
may become necessary.
• In order to ensure long life of this product, the sample uid should be
removed as soon as possible after measurement and replaced by a suitable
uid that serves to clean the system and does not cause corrosion (such
as pure water, alcohol, or similar). When doing this, care must be taken
to avoid adverse reactions due to unsuitable uid combinations.
• Depending on conditions such as the liquid type, concentration, and tem-
perature, the sample uid may gradually corrode the uid-contacting parts,
leading to leaks. It is therefore essential to carry out regular inspections.
• Store the unit in locations within the prescribed temperatures and humid-
ity ranges (-10°C to +50°C, 90% RH and less).
• Use the unit in locations within the prescribed temperatures and humidity
ranges (+15°C to +35°C, 80% RH and less).
If the temperature of the sample uid is lower than the environmental
temperature, condensation may occur. Take suitable countermeasures
such as using purge gas (refer to the section “Precautions against con-
densation” on page 10).
• Do not use or store the unit in locations which
- may be subject to condensation by sudden changes in temperature, or
- may be subject to splashes of water or other uids, or
- may be subject to direct sunlight, or
- may be subject to air with high salt or sulfur content, to corrosive
chemicals, or to gases, or
- may be unstable or inclined, or
- may be subject vibrations or shock.
• If the unit is used in a manner not specified by the manufacturer, the
protection provided by the unit may be impaired.

xiii
• If sample uid has accidentally entered other part of the unit, there may
be a risk of re. Disconnect the connection cable immediately from the
CONTROLLER connector of the unit.
• If the unit operates abnormally, disconnect the connection cable from the
CONTROLLER connector of the unit.
• Before using the unit, make sure that all cord, cable and tube connections are
correctly and safely established. Do not subject the cords, cables and tubes to
excessive bending or other force. When disconnecting the cords, cables and
tubes, disconnect while holding onto the end of the plug, connector or tube.
• Be aware of the possibility of leaks from uid system parts such as
tubes, connectors, and the syringe of the syringe sampler. These parts
are consumables and must be regularly replaced.
• Excessive electrical noise or voltage uctuations can cause a malfunction
or a failure.
• Do not disassemble the unit or attempt internal alterations. If a malfunction
should happen to occur, do not try to solve the problem on your own, but
rather note the condition of the unit clearly and contact the supplier.
• The end plugs are required to seal the unit when storing or returning it for
maintenance or servicing. Store the plugs in a safe location for later use.
• The sample uid system of the unit must always be lled with uid (during
measurement, storage, and transport). If the sample uid system dries up,
ow cell problems (see page 7) can occur.
• When the unit is not installed in a clean room environment, airborne
contamination that entered in the case may adversely affect the measurement
or may cause the malfunction of the unit. To prevent this, please clean
the unit with the purge gas during installation.
• Before returning the unit for maintenance or servicing, thoroughly purge
the piping with pure water. Then ll the piping with clean ethyl alcohol
and install the end plugs. In addition, use the special packaging box so as
to prevent the unit from being subjected to vibrations and shock. When
sending the units, please follow any related laws and regulations, and the
instructions of your shipping carrier.
• When disposing of the unit, be sure to observe all applicable legal regulations
and guidelines in your country and community.

Outline
The KS-19F is a sensor which uses the light scattering method for measuring
the particle number concentration in liquid. The particle count is determined
for various sizes. Sample uid contacting parts are made of sapphire and PFA,
allowing direct measurement of hydrouoric acid.
By connecting the KS-19F to the optional controller KE-40B1, a liquid-borne
particle counter system with up to ten size ranges can be created.
Using the KE-40B1, it is also possible to freely specify the size ranges 0.03
μm to 0.13 μm for particle detection. The factory default setting is four chan-
nels (≥0.03 μm, ≥0.06 μm, ≥0.1 μm, ≥0.13 μm).
The ow rate is 10 mL per minute, and counting efciency is 5%. The effec-
tive ow rate at which particles are detected and measured is the ow rate
multiplied by the counting efciency, i.e. 0.5 mL per minute.
The KS-19F does not have measurement controls or a display for measure-
ment results. It is designed to be used under control of a separate controller
KE-40B1 which also supplies power to the KS-19F.
The KS-19F incorporates a leak sensor. If a leak is detected, an alarm output
can be activated.
As the KS-19F does not incorporate a ow control circuit for the sample
uid, the ow rate of the sample uid must be controlled by external means.
Light source service life
The KS-19F uses a diode pumped solid state laser as a light source.
The life expectancy of a laser diode for pumping is shorter than that of other
semiconductors. When the laser diode nears the end of its service life, the
optical power falls below the rated level. There are considerable differences
in service life between individual diodes.
The KS-19F detects when the laser diode no longer provides the required
output. In such a case, the LASER indicator of the KS-19F and the [LASER]
icon of connected controller KE-40B1 display ash in green, which indicates
that the laser diode must be replaced.

Outline
Particle size detection
The KS-19F is calibrated at the factory, using particles of known diameter
and refractive index (monodisperse polystyrene latex spheres with a refractive
index of 1.6) in pure water. As the amount of scattered light by such particles
is used as reference to determine the particle size, the measured size corre-
sponds to the light scattering size of polystyrene latex particles.
Leak detection
The KS-19F incorporates a leak sensor. If a leak is detected, the LIQUID
LEAK indicator lights up in red and the LIQUID LEAK ALARM terminals
become OPEN.
To ensure that the leak sensor operates properly, the KS-19F must be placed
on a horizontal surface (inclination within 2 degrees). For proper activation
of the leak sensor, the leak sample uid must be held at the bottom of the
KS-19F.
Caution
If a leak is detected, stop the sample uid
supply to the KS-19F and disconnect the
connection cable from the CONTROLLER
connector of the KS-19F. When any sample
uid has accumulated in the KS-19F, contact
your supplier.
