Conductivity Probe

The Conductivity Probe determines the ionic content of an aqueous solution by measuring its conductivity. This has many applications in chemistry, biology, and environmental science.

SKU: CON-BTA Categories: ,


The Conductivity Probe has three ranges, providing optimal precision in any given range. Biology teachers can use this probe to demonstrate diffusion of ions through membranes. Chemistry students are able to quickly investigate the difference between ionic and molecular compounds, strong and weak acids, or ionic compounds that yield different ratios of ions. Environmental science students use it to measure TDS, total dissolved solids.


Range:Low Range: 0 to 200 μS/cm (0 to 100 mg/L TDS)
Mid Range: 0 to 2000 μS/cm (0 to 1000 mg/L TDS)
High Range: 0 to 20,000 μS/cm (0 to 10,000 mg/L TDS)
