School Savers - Vernier CON-BTA Conductivity Probe

Vernier CON-BTA Conductivity Probe

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.

Additional Features
Fast response time: Reaches 98% of full value in less than 5 seconds.
Quick and easy calibration using our software.
Built-in temperature compensation allows you to calibrate the probe in the lab, and then make measurements outdoors without temperature changes affecting data.
Alternating current at its electrodes preventing polarization and electrolysis, reducing contamination of solutions.
Epoxy-body graphite electrode eliminates worry about corrosion of metal electrodes.
