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.
Description
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.
- ABS-body graphite electrode eliminates worry about corrosion of metal electrodes.
