The Hanna Instruments HI 711 Total Chlorine Handheld Colorimeter 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.

The Hanna Instruments HI711 portable handheld colorimeter features a resolution of 0.01 ppm and ±0.03 ppm (mg/L) ±3% of reading accuracy. The Hanna Instruments HI-711 also uses an EPA approved DPD method. The contoured style of the Checker HC fits in your palm and pocket perfectly and the large LCD is easy to read. The auto shut-off feature assures the battery life will not be drained if you forget to turn it off.

The Hanna Instruments HI 711 Total Chlorine Colorimeter is extremely simple to use. First, zero the instrument with your water sample. Next, add the reagent. Last, place the vial into the Checker HC, press the button and read the results. It's that easy.
