Hanna Instruments HI-727 Colour Of Water Checker
The Hanna Instruments HI-727 Checker®HC provides a simple, accurate and cost-effective way to measure the colour of water.
Used in drinking water and wastewater, the colour of water may indicate the presence of undesirable and potentially harmful material, such as organic matter.
True colour is caused by dissolved compounds in water. It can be natural or artificial. Dissolved and suspended solids (together) cause apparent colour.
Other harmless constituents of water such as tannins, iron and manganese, may also be present and impart colour. The HI-727 reports the colour of water from 0-500 PCU (Platinum Cobalt Units).
