ULR CL17sc online ultra-low range total chlorine analyzer

Instrument Features:

• Can accurately detect chlorine content in water above 8 ppb, monitor and optimize the dechlorination process.

• Uses the DPD colorimetric method to directly measure total chlorine content in water.

• The cumulative chlorine content function allows customers to understand the real impact of chlorine content passing through the reverse osmosis membrane, thereby more accurately predicting the efficiency and service life of the reverse osmosis membrane.

Measuring method:

Total chlorine: N,N-diethyl-1,4-phenylenediamine photometric method (DPD method)
