Don’t strain your eyes reading a scale—these bench-top meters indicate exact results on the digital display. For complete resistance to dust and protection from temporary submersion, these meters float and have a housing that meets NEMA 6 and IP67. They're for use with water and other 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.

Upload up to 500 conductivity and total dissolved solids (TDS) readings to a PC. This meter has a probe on a 3-ft. cable for taking readings in hard-to-reach areas. It's for use with tap water, pool water, hydroponic solutions, and other clean liquids. Automatic temperature compensation standardizes readings at 77° F to prevent inaccurate results in fluctuating temperatures. Data hold freezes the current reading on the display. Use a Calibration Solution (not included) and the calibration button to maintain accuracy.

Since this oxidation reduction potential (ORP) meter has a housing that meets IP67 for complete resistance to dust and protection from temporary submersion, it’s often used to determine a solution’s ability to break down contaminants in harsh field conditions. For use with dirty liquids containing heavy metals, sulfides, and harsh chemicals, this meter is often used for wastewater treatment. 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.

Transmit pH readings to a PC for analysis. This meter has a sensor on a 3-ft. cable for taking remote readings of water and other clean liquids. It has automatic temperature compensation that standardizes readings at 77° F to prevent inaccurate readings in fluctuating temperatures. Use a Calibration Solution (not included) and the calibration button to maintain accuracy.
