Conductivity Tester

Quick Answer: Conductivity Tester is a handheld, 12V battery-powered instrument that gives a quick visual, LED-scale comparison of how well solids, solutions, acids or salts conduct electricity.

This instrument from EduScope India's electronic lab instruments India range under Physics Lab Equipment is built to give a qualitative visual indication of conductivity, rather than a precise numeric reading. It offers a quick, at-a-glance comparison between solids, solutions, acids, and salts, making it a handy first check on the bench before more detailed measurement is needed. The tester uses two brass probes, each 53mm long and 3mm in diameter, that make direct contact with the material being tested; together with the meter body, the overall probe-and-meter length is 14cm. The unit runs on an included 12V battery and comes complete with operating instructions to guide first-time use in the lab. To test a sample, the two probes are touched to a solid substance or immersed together in a liquid; as conductivity increases, a row of green LEDs numbered 1 to 10 lights up further along the scale, giving students an immediate visual comparison between different materials or solutions without needing to read or interpret a numeric meter.

It is part of EduScope India's Physics Lab Equipment range. For a related setup involving electrolyte solutions and electrical behaviour, see the Equipotential Trough Kit. Students who want precise numeric readings alongside this device's quick qualitative check may also refer to EduScope India's Multimeter, Digital.
