The HI701, HI7014, and HI762 Checker®HC 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 of resolution, while professional instrumentation can cost hundreds of dollars and can be time consuming to calibrate and maintain. These meters are accurate and affordable. The HI701 and HI7014 features a resolution of 0.01 ppm and ±0.03 ppm ±3% of reading accuracy while the HI762 features a resolution of 1 ppb and ±20 ppb ±4% of reading accuracy. These meters use an EPA approved DPD method. The contoured style of the Checker HC fits in your palm or 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. These meters are extremely simple to use. First, zero the instrument with your water sample. Next, add the reagent. Lastly, place the vial into the Checker HC, press the button and read the results. It’s that easy.
