Ideal for Water Quality
True color is caused by dissolved compounds in water. It can be natural or artificial.  Dissolved and suspended solids (together) cause apparent color. Color is measured in Platinum-Cobalt units. The AWWA recommends ≤ 15 PCU.

The HI 727 Checker®HC is extremely simple to use. First, zero the instrument with deionized water. Next, prepare the sample according to the Apparent/True color measurement. Place the second vial with prepared sample into the Checker®HC, press the operational button and the
HI 727 Checker®HC displays the color of water in PCU.
