Product Description

Phosphorus concentration in water is monitored because it causes corrosion when present in levels too high.

The NDHI 706 Checker®HC is extremely simple to use. First, zero the instrument with your water sample. Next, add the reagents. Last, place the vial into the Checker®HC, press the button and read the results. It’s that easy.
