FINALLY! An accurate way to measure, control, and document your stabilized bromine product.
Free bromine sensors don’t work, ORP doesn’t work, Walchem has a sensor that does. Just supply a clean sample of cooling tower water and calibrate to match your normal DPD-4 test. It can be installed the same way as our other membrane-style amperometric disinfection sensor, or the sample can be returned to a pressurized pipe up to 85 PSI.
