The online L360Cl analyzer measures chlorine in water by means of the industry-standard colorimetric DPD method. Prior to adding reagent, the optics are calibrated at 0% and 100%T (both ends of the scale) for measurement consistency. The L360 design assures that the optical path is wiped clean before every test. Only microliters of reagent are required for each test, conserving reagent. With its auto dilution feature, the L360 accommodates both low and high process ranges. For dependable process control, each analysis can be automatically replicated prior to posting or alarming. Reagent consumption is minimized with microliter fluid delivery. Grab sample and auto standard validation are available as an option. Output options include Modbus, current loop, and relay.
