Water-Quality Test Kits

Analog

Digital

All the chemicals and labware you need for on-site sampling and water-quality testing.

Digital kits offer simpler and more accurate testing than analog kits. While analog kits require you to visually match color against a chart, these kits electronically measure color for you, even in dim lighting. The digital screen shows you a precise measurement.

Water-Quality Combination Test Kits

Test for contaminants before installing water-treatment equipment such as boilers and filters. You can also check your pipes and equipment for improper chemical levels that can cause corrosion and scale buildup, shortening their life.

367-test kits include tests for six common water-quality parameters in boiler systems and cooling towers.

340-test kits include tests for monitoring municipal water, which is often treated with chlorine.

290-test kits include tests that help you monitor well water, which often contains sulfur compounds.

Water-Quality Test Strips

Dip these strips into your liquid to quickly test water conditions. Strips change color to indicate the value reached; match the color of the strip to the color chart on the bottle to interpret the results.
