Safety precautions
This section provides precautions to enable you to use 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 and receiving
instrument side of the converter.
Electric shock hazard
Be sure to turn OFF the power before wiring power source.
Be sure to ground the grounding terminal. (The ground resistance shouldbe 100 Ωor less.)
To connect any load exceeding the contact capacity or any induction load (e.g., motor, pump), be sure
to use a power relay.
Beware of strong acid
When handling nitric acid, be sure to wear protective goggles and gloves.
If it gets into your eyes, it could cause irritation to the mucous membrane and the loss of eye sight. In
order to avoid this, immediately rinse your eyes with a large quantity of running water for at least 15
minutes and quickly seek medical help. When rinsing your eyes, open your eyelids well with your
fingers so that water can reach the eyeballs and the entire eyelids. If the nitric acid touches your skin
or clothing, it could cause burns. In order to avoid this, immediately take off your clothes and rinse off
the nitric acid with a large quantity of running water.
CAUTION
Take extra care when installing the sample inlet piping. If the piping is disengaged when the pressure
increases with the operation of the flow rate adjustment valve, serious accidents may occur.

Product Handling Information
Operational precautions
Use of the equipment in a manner not specified by the manufacturer may impair the protection
provided by the equipment. And it may also reduce equipment performance.
zDo not press any operation key with the tip of your nail or anything pointed.
zDo not use solutions such as organic solvents.
zWhen cleaning the measuring cell, be extremely careful not to scratch the brownish-red
area of the anode and reference electrode surfaces.
zDirect sunlight will reduce the silver chloride covering the reference and anode electrode.
Install the sensor in a room to avoid direct sunlight.
zBe sure not to scratch or contaminate the gold electrode section on the cathode surface.
If the surface of the gold electrode is scratched, it affects the reading.
zWhen reattaching the bead cell, confirm that there are no beads inside the measuring cell
and around the O-ring, and then push it into the measuring cell.
zGradually open the supply source valve. If you open it abruptly, the flow rate or pressure
exceeds the specified level. In such a case, the beads may pop up from the bead cell.
Open the sampling valve slowly. Fully open valve passes excessive flow rate that kicks
out the ceramic beads from the bead cell. The adequate flow rate is 0.1 L/min to 0.5 L/
min.
zDo not touch the rotating electrode.
Disposal of the product
When disposing of the product, follow the related laws and/or regulations of your country for
disposal of the product.
This product includes the lead battery of uninterruptible power supply system and the
tungsten lamp of the microscope light.

Overview
1
Overview
This is a residual chlorine meter with no chemical treatment to the sample. The main
components are the transmitter HR-200RT, the detector unit, measuring cell and some
peripheral units. It is suitable to monitor the residual chlorine concentration for those samples;
city water, swimming pool water, public bath and DI water plant using hypochlorite for
sterilization. The measuring range is 0 mg/L to 3 mg/L for residual chlorine and 0°C to 45°C.
The measuring principle is 3-pole polarograph method with the gold cathode electrode, silver
anode electrode and silver/silver chloride reference electrode. The temperature is measured
to compensate sensitivity influenced by sample temperature. If the sample pH is not steady,
the function to compensate the influence by pH is provided with the information from the pH
meter aside via RS-485 digital communication.
The replaceable cathode electrode attached to the rotating shaft is always polished in the
ceramic beads to be protected from metal plating on the surface.
The zero point is calibrated by the water through activated carbon filter. The manual operation
needs to change the line to pass the water through the activated carbon filter manually and
confirm the reading is near to zero before zero calibration. The sampling pipe works with the
optional solenoid valve will change the line periodically and automatically for zero calibration.
The sensitivity is calibrated by the way to match measured value to the analyzed value by
adjusting the coefficient.
The two line analog outputs transmit the trend of residual chlorine and temperature. The
output range of the current 1 is selectable by the external contact. The four contacts output the
upper or lower alarm for residual chlorine and temperature, control signal for residual chlorine,
holding signal, calibrating signal and error signal.
Those peripheral units are provided; the filter unit to remove dust, the flow switch to detect
flow, the flow meter unit to measure sample flow rate, the activated carbon filter unit to remove
residual chlorine, the auto zero calibration unit to control line for zero calibration.
