HR-200RT

Field-installation Type Residual Chlorine Meter (Four-Wire Transmission, Rotating Type)

HR-200RT is connected to a residual chlorine sensor (RA-30), which allows the free residual chlorine concentration to be measured with high accuracy. It is sutable for waterworks, pool water sterilization, and desalination systems. The measurement method is a three-pole polarographic method, which enables continuous monitoring of residual chlorine concentrations without using reagents.
Stable measurement over a long period was realized by physical polishing cleaning using beads.

1: If use our designated flow switch (RA-FS30), regulate flow rate in 0.3 L/min to 0.5 L/min.
2: The measurement section is under an open air environment.
3: If pH of the measured sample varies, the value of residual chlorine also varies. Perform measurement in an environment in which pH variations are less likely to occur.
4: Measurement cannot be performed correctly when the electrical conductivity falls below 8 mS/m (80 S/cm). Be sure to perform measurement in this conditions.
5: If the electrode is exposed to the direct sunlight, the anode and cathode electrode could deteriorate. Install the instrument where it is not exposed to direct sunlight (indoors).
6: If a reducing agent or oxidizer exists in a sample, it affects the reading. Do not use a sample containing a reducing agent such as thiosulfate or sulfite, or oxidizer such as O3, hydrogen sulfide or chlorine dioxide, as measurement cannot be performed correctly.
