The HI-761 Checker is a simple, accurate, and cost effective way to measure ultra-low ranges of total chlorine.
Designed as a more accurate alternative to chemical test kits, the HI-761 provides quick, accurate results in four easy steps.
The HI-761 uses an adaptation of the USEPA method 330.5. The reaction between the chlorine and DPD reagent causes a pink tint in the sample.
