The amperometric based three electrode measure cell is designed to continuously analyze free or total chlorine over the range of 0-20 mg/L. The measure cell is panel mounted and comes complete with a built-in pressure reducing valve to control sample inlet pressures up to 150 psi. A flow switch is included to alert the user in case of sample flow failure. A third electrode is utilized in the CL1 measure cell to further bias and stabilize the chlorine readings. Reagents are fed by a peristaltic pump assembly for up to a maximum 5 week supply of reagent(s). Water sample temperatures are measured, displayed and
allow for automatic compensation of the chlorine levels. Optionally, an additional 12 mm electrode can be inserted into the sample inlet area allowing for example the capability to measure pH as well.
