Compact Chlorometer Duo
For true field versatility, the Compact Chlorometer Duo cannot be beaten, delivering dual range chlorine analysis for the widest variety of applications.
The Compact Chlorometer Duo offers an ideal answer to chlorine testing requirements. The instrument is suitable for either field or bench use across all applications.

Whether testing drinking water compliance using the DPD method or measuring higher levels of chlorine concentration for process applications via the Chlorine HR method, the Compact Chlorometer Duo provides both. Key features of the product include:

    • Simple operation – blank or measure with a single button
    • Waterproof and battery powered – ideal for field use
    • Measure chlorine up to 250 mg/l on one meter.
