ACCURATE AND AFFORDABLE IODINE MEASUREMENT
Iodine is sometimes used as a disinfectant for potable and swimming pool and spa waters. It has also found use as a disinfectant in the poultry industry. The rapid determination of Iodine is required for adequate control of this bactericide. The HANNA HI 718 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 718 Checker®HC is accurate and affordable. The HI 718 Checker®HC portable handheld colorimeter features a resolution of 0.1 ppm (250 points) and 5% ±0.1 accuracy of reading. The HI 718 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 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 HI 718 Checker®HC, press the button and read the results. It’s that easy.
