L450 Chlorine Analyser

The online L450CL analyser measures chlorine in water by means of a complete chlorine reduction with buffered iodine ion followed by a robust, differential endpoint back titration with buffer and thiosulphate oxidiser.

With differential endpoint detection method, the internal Pt electrode does not require calibration or replacement and electrode cleaning requirements common with other methods are eliminated.

No colourmetric dyes or indicators are required. For dependable process control, each analysis is automaticlly replicated and/or trend checked prior to posting, alarming or replenishing.
