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.
