Maintenance Detector unit maintenance procedure This section describes the maintenance procedures for the residual chlorine detector. Checking the sample flow rate Fluctuations in the sample water flow rate affect the reading of the residual chlorine sensor. A decrease in the flow rate due to clogging of the piping could cause a decrease in the reading value.
Maintenance Removing the detector contamination Physical polishing/cleaning using ceramic beads is performed for the detector unit. If any hard-to-remove contamination adheres to the cathode electrode surface, it may largely affect the measurement results. If the reading value drops or any abnormality is visually detected, clean the cathode electrode according to the following procedure.
Page 59
Maintenance 5. Rinse off the contamination from the surface of the cathode electrode. WARNING 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.
Maintenance Cleaning procedure for other electrodes wipe the surface of the anode and cathode electrode with absorbent cotton wetted by alcohol. Note The silver chloride will deposit on the surface of the anode electrode according to the progress of measurement. Too thick silver chloride layer will reduce the contact area of the silver and the sample water, then the electrons which cover the cathode reaction will not be sufficient.
Maintenance Cleaning the measuring cell Since water stain adheres to the inside of the measuring cell as time goes along, clean it periodically. 1. Detach the connector cable to stop cathode rotation. 2. Close the valve to stop the sample supply. 3.
Maintenance Restarting the measurement 1. The inside of the detector may be contaminated while the operation is paused. Remove the contamination of the detector, clean/replace the bead filter A, bead filter, clean the measuring cell, and replace the filter (option) as necessary. Refer to “...
Maintenance Calibration There are three types of calibration: zero solution calibration, span calibration, and temperature calibration. You have to confirm the reading is stable before calibration. Residual chlorine concentration calibration There are two types of residual chlorine calibration: zero solution calibration and span calibration.
Page 64
Maintenance Zero calibration Zero solution refers to a sample whose residual chlorine concentration is 0.00 mg/L. Zero solution calibration can be performed with higher accuracy by passing the zero solution through the measuring cell. 1. Switch to the cal mode by performing the operation described in “ Calibration ” (page 53), and to the zero solution calibration screen.

Data Technical data What is residual chlorine? Residual chlorine refers to hypochlorous acid, which is generated when a chlorine agent is dissolved with water, and chloramine, which is generated when hypochlorous acid is combined with ammonia. The former one is called “free residual chlorine”, and the latter one is called “combined residual chlorine”, and they are collectively called “residual chlorine”.
Data Measurement principle The measuring principle of the HR-200RT is three-electrode polarograph method. Gold is used for the cathode electrode and silver/silver chloride is used for the anode electrode and for the reference electrode. This method can control the potential difference to be constant between cathode electrode and the sample with reference electrode as a probe of detecting sample potential.
Data Sample liquid conditions Influence of the pH of the sample The chemical form of free residual chlorine varies depending on the pH of the sample, as described in the previous section. Fig. 3 indicates variations in the readings of the converter due to a change in the pH values. As indicated in Fig.
Page 81
Data Influence of the temperature of the sample With the polarographic method adopted by the converter, readings are affected by the temperature of the sample. There are two reasons for this fact: (1) as the diffusion coefficient depends on the temperature, the obtained diffusion current also changes (2) the chemical equilibration of the hypochlorous acid depends on the temperature.
