WARNING
Sample fluid danger prevention
When toxic sample fluid comes into contact with any part of the human body
or when toxic gases generated by the sample fluid are breathed, there is a
danger of severe injury or death.
When sample fluid comes into contact with other objects in the vicinity, there
is a risk of fire, explosion, corrosion, deformation or other effects.
Observe the following points closely to prevent the danger of sample fluid
leaks and sample fluid accretion.
zDo not pass sample fluids which can cause corrosion of fluid-contacting
parts (PFA, sapphire) through the system.
zObserve the following points when setting up or dismantling a measurement
system.
- Check the sample fluid for any risks due to toxicity or other harmful
properties.
- Make sure that sample fluid cannot leak from the system and come
into contact with body parts, clothing etc.
- When attaching or detaching tubes, connectors etc., always use
appropriate protective tools and wear dual-layer gloves.
- Double-check all connections before starting the sample fluid flow.
zSince the unit does not incorporate a leak sensor or other safety device,
perform a thorough leak check to verify safety before starting operation.
zThe pressure of sample fluid passed through the unit may not exceed
300 kPa (gauge pressure). Ensure that the supply system (sampler,
sample fluid lines etc.) has sufficient pressure resistance.
zWhen using sample fluid which may produce harmful gases, provide
adequate ventilation as prescribed by applicable laws and regulations.

v
zBefore and after measurement, clean the entire sample fluid 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 fluids.
zBefore starting to prepare the system for storage, complete the cleaning
process with pure water and verify neutrality (pH7).
zDispose of waste sample fluid only as prescribed by applicable laws and
regulations.
zNever mix waste sample fluid with other substances unless absolute safety
has been established.

Outline
The KS-16F is designed to be used as an in-line sensor in a system for measuring
the size and number of particles in liquid, using the light-scattering method.
Measurement results are output via a built-in interface. The KS-16F consists
of the sensor unit and the power supply unit. Particles are measured in five
size ranges (≥0.1 µm, ≥0.15 µm, ≥0.2 µm, ≥0.3 µm, ≥0.5 µm), and the sample
flow rate is 10 mL per minute.
The KS-16F does not have measurement controls or a display for measurement
results. It is designed to be used under control of external equipment such as a
computer, and to send measurement results to the external equipment A standard
serial interface and a special Rion multi-point interface for multi-point
measurements are built in.
As the KS-16F does not incorporate a flow control circuit for the sample fluid,
the flow rate of the sample fluid must be controlled by external means.
Types of sample fluids
This unit is designed to detect the size and number of particles floating in
liquid. Never use the unit with the liquid types listed below, to prevent the
possibility of accidents and damage to the unit.
- Explosive liquid or mixtures containing explosive liquid
- Liquid which can cause corrosion of fluid-contacting parts or mixtures
containing such liquid
- 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)
- Liquid which may have effects such as thermal build-up, hardening,
and particle accumulation. Always clean the system thoroughly before
using a different liquid.

Outline
Laser source service life
The life expectancy of a laser diode such as used in the KS-16F is shorter than
that of other semiconductors. When the laser diode nears the end of its service
life, the light output falls below the rated level. There are considerable
differences in service life between individual diodes. Some may fail already
after several thousand operation hours. The KS-16F detects when the laser
diode no longer provides the required output. In such a case, the LD indicator
flashes in red, which indicates that the laser diode must be replaced.
Transport
Before returning the unit for
maintenance or servicing, purge the
sample fluid system thoroughly
with pure water to remove any
sample fluid remnants. Then fill
the piping with alcohol (or ethyl
alcohol) and seal it with the end
plugs. Wipe the outside of the unit
clean so that there are no remnants of chemical substances on the unit.
The label shown at right is affixed to the top of the unit.

Outline
Particle size detection
The unit is calibrated at the factory, using particles of known diameter and
refractive index (single 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 corresponds to the
light-scattering size of polystyrene latex particles.

Outline
Measurement system configuration example
With the KS-16F, measurement control and processing of measurement results
are entirely performed by a computer. A basic measurement configuration using
the serial interface is shown below. Configure your actual system according to
the measurement requirements and types of sample fluid.
For details on how to perform measurement control and how to read measurement
results etc., please refer to the section "Serial Interface" on page 23.
It is also possible to configure a multi-point monitoring system using the Rion
multi-point interface. For details, please refer to the section "Multi-point
Monitoring System" on page 45.
Important
Do not use the serial interface and the multi-
point interface at the same time. Correct opera-
tion of the unit is not assured if control is at-
tempted via both interfaces.
The service life of the light source (laser diode)
is limited. While no measurement is being car-
ried out, the light source should be turned off as
much as possible.
