HC Handheld Colorimeter - Total Chlorine, Checker® - 0.0 to 3.50 ppm - HI711

The HANNA HI 711 Checker® HC bridges the gap between simple chemical test kits and professional instrumentation. Chemical test kits are not very accurate and only give 5 to 10 points resolution while professional instrumentation can cost hundreds of dollars and can be time consuming to calibrate and maintain. The HANNA HI?711 Checker®HC is accurate and affordable. This Checker®HC portable handheld colorimeter features a resolution of 0.01 ppm and ±0.03 ppm (mg/L) ±3% of reading accuracy. It also uses an EPA approved DPD method. Ideal for: Swimming pools and spas, fruit and vegetable sanitation, disinfection, drinking water and quality control checks.
