Water-Resistant pH Meters

Check pH in harsh field conditions. These floating meters that have a housing that meets IP67 for complete resistance to dust and protection from temporary submersion. Automatic temperature compensation standardizes readings at 77° F to prevent inaccurate results in fluctuating temperatures. Use a calibration solution and the calibration button to maintain accuracy. They do not include Calibration Solution.

For Testing pH

For Use With Clean Liquids—Meter for clean liquids is commonly used in pools and hydroponic solutions.

For Use With Dirty Liquids—Meter for dirty liquids stands up to wastewater, plating bath solutions, and other harsh liquids.

Cannot Be Sold to Canada—Meters cannot be sold to Canada due to import regulations.

pH Meters

More precise than test strips, these meters are often used to measure the pH of dirty liquids in agricultural systems, aquaculture tanks, and printing fountains. 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.

Water-Resistant Conductivity Meters

Don’t worry about dropping this meter in your tank when checking electrical conductivity—it floats and has a housing that meets IP67 for complete resistance to dust and protection from temporary submersion. For use with water, hydroponic solutions, and other clean liquids, this meter measures a liquid's conductivity to indicate the concentration of salts, nutrients, chemicals, and other substances. It displays temperature in addition to conductivity. 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.

Remote-Reading pH Meters

Monitor pH readings from your smartphone or tablet—download the app to view data up to 160 ft. away using Bluetooth. Made of durable nonglass, the sensor resists breaking. They are for use with dirty liquids, so they stand up to petrochemical, environmental, and agricultural testing. Rated IP67, they seal out dust and withstand temporary submersion. Use a calibration solution (not included) and the calibration setting in the app to maintain accuracy.
