Safety precautions
This section provides precautions for using the product safely and correctly and to prevent
injury and damage. The terms of DANGER, WARNING, and CAUTION indicate the degree of
imminency and hazardous situation. Read the precautions carefully as it contains important
safety messages.
WARNING
If there is a possibility of a lightning strike, install an arrester on the output side of the converter and on
the side of receiving instruments.
Electric shock hazard
Be sure to check that no electric power is supplied before starting the procedure.
Electric shock hazard
Be sure to ground the earth terminal (ground resistance of 100 or less) for safety.
To connect a load greater than the contact capacity or an induction load (e.g., a motor or a pump), be
sure to use a power relay rated higher than the load rating.
Caution strong acid
If nitric acid gets into the eye, irritation of the mucous membrane and even blindness may result.
In handling nitric acid, be sure to use protective goggles and mask. If nitric acid gets into the eye,
immediately rinse it out with plenty of water for more than 15 min, and then get medical care (In
rinsing out nitric acid, ensure that the eyeball and the eyelid are entirely exposed to water by fully
opening the eyelid with your fingers). If nitric acid remains in contact with body and clothes, chemical
burns may result. Therefore, if a spill or splashing occurs, immediately take off the clothes and rinse
off the nitric acid with plenty of water.
CAUTION
Sample inlet to the flow control valve may be pressurized, careful pipe works are required to ensure
safe sealing.

Product Handling Information
Operational precautions
Use of the product in a manner not specified by the manufacturer may impair the protection
provided by the product. And it may also reduce product performance.
Exercise the following precautions:
Do not press any operation key with the tip of your nail or anything pointed.
Do not use any organic solvent.
To loosen four M4 screws, hold the measurement cell. Failure to observe this instruction
may cause the cell to drop and be damaged.
To remove the measurement cell, be sure to pull it down straight. Failure to observe this
instruction may result in breakage of the measurement cell nozzle.
When cleaning the measurement cell, take care not to damage the brown-colored parts
on the anode electrode and the reference electrode.
The surface of the reference and anode electrode will be reduced into silver if the
electrodes are exposed to the direct sunlight. Avoid direct sunlight to the sensor unit.
Avoid scratch and dirt on the gold surface of the cathode electrode. The dirt on the gold
will affect measurement precision.
When the beads are replaced, make sure that no beads are stuck around the O-ring and
upper part of the bead cell.
Open the sampling valve with care. Sudden opening will disperse beads to the any part
out of the circulation path in the measuring cell.
Disposal of the product
When disposing of the product, follow the related laws and/or regulations of your country.

Overview
Introduction
The HR-200 is designed to measure the concentration of free residual chlorine accurately
contained in tap water, swimming pool water, public bath water, or the like. The measuring
principle is three-pole polarography method without any treatment by reagents for simple
measurement of residual chlorine. In addition, combination of beads cleaning and electro
chemical cleaning enables stable measurement over a long time. In principle, constant flow
rate is required for stable measurement. For the stable flow rate, we offer two types of
measurement cell. The RA-10 is over flow type sensor that regulates flow rate to the sensor
by built in over flow tank. The RA-20 is in-line type sensor that can measure pressurized
sample with a constant flow valve outside.
Features
The converter has a splash-proof construction compliant to IP65.
Simultaneous temperature display can be selected.
All settings can be operated using the front keys.
Improved maintenance (self-diagnostic function).
Free setting transmission output range.
Nonvolatile memory.
Easy-to-view display (150larger than the previous model).
Improved operability of keys using an emboss sheet.
Improved mode display using icons.
The sensor ensures stable and accurate measurements.
Easy maintenance.
A suitable measurement cell can be selected for the process.
The HR-200 requires no reagent, eliminating troublesome operations such as supplying
reagents.
The electrode can be changed easily.
The power source is 100 V to 240 V AC 10.

Sensor
(1) Overflow lid
The overflow lid has holes for the installation of the pH and ORP electrodes. To clean the
inside of the overflow cell, remove this lid.
(2) Knurled screw
These screws fix the lid on the over flow cell.
Loosen the screws slightly to pick up the lid. The screws should not be removed to avoid
missing.
(3) Overflow cell
This cell is used to ensure a stable flow rate in the measurement cell.
Even if the flow rate at the sample inlet fluctuates within the specified range (1.3 L/min to
2.0 L/min), the flow rate in the measurement cell can be maintained at a constant level.
(4) Converter cable
This cable is connected to the converter (HR-200).
(5) Measurement cell
This cell is used to abrasively clean the sensor surface by shooting out beads while
exposing the cathode electrode surface to the sample at a constant flow rate.
(6) Stop valve (flow control valve)
This valve stops or controls sample flow to the residual chlorine sensor.
Note
For the overflow type RA-10, adjust the flow rate of the sample at 1.3 L/min to 2.0 L/min.
For the inline type RA-20, adjust the flow rate of the sample at 0.8 L/min.
Sampling pipe work should be according to the PVC piping for tap water.
The quality and residual chlorine ranges of the sample are specified in the specifications.
Do not supply water out of the specification. Sample water out of the specified quality can not be
measured accurately.
(7) Sample inlet
Supply sample water to this port. The inlet is TS16 (tapered socket 16) for PVC pipe.

(8) Beads cell
This cell contains beads that are used to abrasively clean the cathode electrode surface.
Beads can be easily replaced by loosening the thumbscrew at the bottom of the beads
cell (which will not fall off), and then drawing out the cell toward you.
Note
An O-ring (S30) is used for sealing bead cell and measuring cell; Keep it for reuse.
(9) Anode electrode
(10) Electro chemical cleaning electrode (EC electrode)
This electrode is used to generate negative potential to the cathode electrode so that
metallic contamination on the cathode electrode surface, which cannot be removed by
beads cleaning, can be removed. The electrode is made of carbon and incorporates a
temperature sensor.
Note
A strong impact may break the electrode.
(11) Reference electrode
(12) Cathode electrode.
Reference
Refer to “ Replacing the sensor (cathode electrode) ” (page 53).
(13) Cleaning beads
These beads are used to abrasively clean the cathode electrode surface.
Reference
Refer to “ Initial setup ” (page 26).
Refer to “ Replacing the cleaning beads ” (page 51).
(14) Sensor cap
This cap is used to fasten the cathode electrode to the measurement cell.
To replace the cathode electrode, remove the sensor cap, draw out the sensor holder, and
then replace only the cathode electrode located at the leading end.
(15) Mounting bracket
This bracket is made of stainless steel, and is used to install the HR-200 on a wall or pole.
To install the HR-200 on a pole, purchase the pole stand and pole installation brackets,
which are optionally available.
(16) Sample outlet
Drain sample water from this port. The outlet is TS16 (tapered socket 16) for PVC pipe.
Reference
Refer to “ Piping for sample outlet (in the case of RA-10) ” (page 16).
(17) Inline cell
This cell is used to send the sample to the measurement cell.
