Custom Conductivity Indicator Electrical Experiment Tester 10 kΩ-20 MΩ

Custom Conductivity Indicator for Electrical Experiment Measurements Power cable is NOT included. Used. See attached photos. Custom conductivity/resistance indicator for electrical experiments and comparative measurement demonstrations, with a labeled resistance range from 10 kΩ to 20 MΩ. This unit appears intended for bench-top educational, electronics, physics, materials testing, and electrical conductivity/resistivity experiments where a visual or comparative indication of circuit/path conductivity is needed across high-resistance ranges. Useful for teaching conductor vs insulator behavior, leakage paths, resistance changes, sensor demonstrations, material comparison, and general electrical lab exercises. Custom-built/non-OEM device; not represented as a calibrated scientific meter. Includes only the unit shown. Please review photos for connectors, labels, condition, and configuration before purchase.
