The HANNA Checker HCs bridge 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 718 and Checker HC is accurate and affordable.
The HI 718 Checker HC portable handheld colorimeter features a resolution of 0.1 ppm and accuracy of Â±0.1 ppm Â±5% of reading. This Checker HC uses a modification of the DPD method used for residual chlorine.
The contoured style of this 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 718 is extremely simple to use. First, zero the instrument with your water sample. Next, add the reagent. Last, place the vial into the instrument, press the button and read the results. Its that easy.
