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.

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.

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

Water-Resistant Multifunction Chemistry Meters

For Use with
Clean
Liquids

Test different water-chemistry measurements in dirty, wet conditions. Often used in pools and spas, all of these meters are for use with clean liquids. Automatic temperature compensation standardizes readings at 77° F to prevent inaccurate results in fluctuating temperatures. Use a calibration solution (not included) and the calibration button to maintain accuracy.

IP57 meters are protected from dust and temporary submersion in liquids.

Chlorine, oxidation reduction potential (ORP), and pH meters come with three sensors that each take one chemistry measurement. They cannot be sold to Canada due to import regulations.

Conductivity, salinity, and total dissolved solids (TDS) meters come with one sensor that takes all three chemistry measurements.

Import regulations restrict sales to the listed areas.
