Iodine - Model HI 718 -Handheld Colorimeter
The HI718 Checker HC (Handheld Colorimeter) provides a simple, accurate and cost effective way to measure iodine. Introduced as an alternative to chlorine, iodine as a sanitizer decreases eye irritation in pools and saps and provides a more stable level of disinfection in adverse conditions. However, due to its toxic and corrosive properties, iodine is strictly monitored. Designed as a more accurate alternative to chemical test kits, the HI718 provides quick, accurate results in four easy steps:
The HI 718 CheckerHC portable handheld colorimeter features a resolution of 0.1 ppm and accuracy of ±0.1 ppm ±5% of reading. This Checker HC uses a modification of the DPD method used for residual chlorine.
The contoured style of this CheckerHC 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. It’s that easy.
