Conductivity Tester, Meter with LED Display, Brass Probes for Solutions, Salts, Lab and Classroom Use

BROAD TESTING VERSATILITY: Functions as an electric conductivity meter for acids, dissolved salts, and conductive solutions - supporting chemistry experiments, water quality assessments, and materials science applications.
CLASSROOM AND LAB READY: At 14cm overall length with 53mm brass probes, this compact conductivity meter fits any lab bench, supply drawer, or field kit - ready for immediate use with no calibration required.

The Electric Conductivity Tester gives educators and lab professionals a fast, reliable way to determine whether a substance conducts electricity - no numerical interpretation required. By immersing the dual brass probes into a liquid or touching them to a solid sample, users receive an immediate visual readout on a 10-point green LED scale, making it straightforward to compare the relative conductivity of solutions, salts, acids, and other reagents across a single controlled experiment.
10-Point LED Scale: A graduated green LED display ranging from 1 to 10 delivers clear, qualitative conductivity readings at a glance - no calibration or data logging needed for rapid comparative testing.
Dual Brass Probes: Two 53mm brass probes accommodate both solid and liquid samples, allowing a single instrument to serve multiple testing scenarios in the same lab session.
Compact Handheld Design: The compact handheld design keeps the unit easy to store, transport, and operate with one hand - practical for benchtop experiments and classroom demonstrations alike.
Battery Included: Ships with a 12V battery and printed operating instructions so the tester is ready to use immediately upon arrival - no additional accessories required.
Broad Application Range: Suitable for testing solutions, salts, and other conductive materials, making it a versatile addition to educational lab kits and research setups.
Unlike digital TDS meters or PPM meters that output numerical concentration data, this tester is purpose-built for qualitative conductivity education - ideal for demonstrating electrochemical principles where relative conductance matters more than precise measurement.
Well-suited for university lab courses, high school science classrooms, and independent researchers, the conductivity meter provides a straightforward, low-maintenance tool for introducing conductance concepts without the complexity of a full EC meter setup.
