Remote-Reading Conductivity Meters

View conductivity readings of wastewater, boiler condensate, aquaculture solutions, and other dirty liquids up to 3 feet from the remote sensor to indicate the concentration of salts, nutrients, chemicals, and other substances.

Conductivity Meters

Check a solution’s electrical conductivity to indicate the concentration of salts, nutrients, chemicals, and other substances.

TDS Meters

Check your system for contaminants with this meter that detects total dissolved solids (TDS) in aquaculture solutions, wastewater, and other dirty liquids.

ORP Meters

Measure a solution’s oxidation reduction potential (ORP) to determine its ability to break down contaminants.

Water-Resistant ORP Meters

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.

Remote-Reading TDS Meters

The remote probe on a 3-ft. cable limits your exposure when taking total dissolved solids (TDS) measurements to determine contaminant levels in aquaculture solutions, boiler condensate, contaminated water, and other dirty liquids.
