The online L450 Chloride analyzer measures chloride in water by means of a selective and accurate titration with silver or mercuric nitrate. With the differential endpoint detection method, the internal Pt electrode does not require calibration or replacement, and electrode depletion and drift common with other methods is eliminated. No colorimetric dyes or indicators are required. For dependable process control, each analysis is automatically replicated and/or trend checked prior to posting, alarming, or replenishing. Sampling can be drawn from pressurized sample stream or pumped from overflow sampler. For sample with particulate, a sample strainer with automatic backflush is offered.
L450Chloride Analyzer has configuration of Base model with standard precision (20 µl) titrant dose pumps, one sample/waste pump, single stream inlet, 4-20 mA output.
