Checker® HC (Handheld Colorimeter) for Chlorine Detection (Hanna Instruments)

This product bridges the gap between simple chemical test kits and professional instrumentation for the detection of free or total chlorine in water. Accurate and affordable, Checker HC portable handheld colorimeters for chlorine detection feature a resolution of 0.01 ppm and an accuracy of ±3% of reading plus ±0.03 ppm (mg/L). They also use an EPA-approved DPD method. The contoured style fits in your palm and pocket and the large LCD is easy to read. An auto shut-off feature prevents the battery from draining if you do not shut off the meter. To use, zero the instrument with the water sample. Next, add the reagent. Finally, place the vial into the Checker HC, press the button and read the results.
