The HANNA Checker®HC’s 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 ±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 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. It’s that easy.
HI 718 Checker®HC is supplied with sample cuvettes with caps (2), powder reagents for iodine (6), battery and instructions.

Hanna Iodine Checker Review by Tim
I was flying blind until I purchased this checker. I was dosing iodide without knowing what my level was. I know dumb, but my reef needed it. I was surprised how easy this test was. 10ml of tank water, one rageant and 3 minutes later you have your reading. Easy as that. Found out that my level was perfect, but this put my mind at ease.
