  • Easier to Use
  • More accurate than chemical test kits!
  • Large, easy to read digits
  • Auto shut-off

 The HANNA HI 721 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 721 Checker®HC is accurate and affordable with immediate results. The new HI 721 Checker HC portable handheld colorimeter features a resolution of 0.01 ppm (5000
points) and ±2% of reading ±0.04 ppm accuracy.

The HI 721 Checker HC uses an adaptation of Standard Method 3500-Fe B. 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 721 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 721 Checker®HC, press the button and read the nresults. It’s that easy.
