Electrodes
Electrodes are produced for optimum use in analytical chemistry and biochemical research. Measure various chemical concentrations, pH levels, conductivity, temperature, gas pressure, voltage, and much more with the variety of electrodes available in our catalog. Rugged digital electrodes are suitable for portable field measurements, and certain models have ports that allow for multiple different electrode sensors to be plugged into a single unit for easy interpretation and analysis of results. Easily find the right electrode model for your laboratory today.

Vernier® High Current Sensor
The High Current Sensor has a range of ±10 A. Current is measured with a Hall Effect sensor, which uses the magnetic field created by the current and therefore does not add a resistive element to the circuit. A metal shield over the Hall Effect chip reduces the influence of external magnets. A replaceable fuse protects the equipment and circuit.
