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.

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 HI 711 Checker®HC 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.
