GTECH - DIGITAL INSULATION TESTER (GTECH -9510) +FREE CALIBRATION CERTIFICATE

The G‑Tech GT‑9510 Digital Insulation Tester is a handheld electrical testing instrument designed to measure insulation resistance of electrical systems, cables, motors, transformers, and other electrical equipment to check the integrity of insulation and help prevent electrical failures. It often includes multimeter functions for versatile electrical diagnostics.

⚙️ Key Features & Functions

• Test Voltages: Typically includes 250 V, 500 V, and 1000 V DC test options — common for insulation resistance testing on industrial and low‑voltage systems.

• Resistance Range: Usually around 0.25 MΩ to ~40 GΩ, allowing evaluation of insulation from poor to excellent condition.

• AC/DC Voltage Measurement: Allows checking supply and signal voltages.

• Resistance & Continuity: Standard multimeter functions for circuit and component checks.

• Data Hold & Display: Keeps the current reading visible for easier recording; typically a large LCD display.

• Auto Power Off: Saves battery when idle.

• Continuity Beep / Indicators: Helps quickly identify open or short circuits.

• Portable Build: Handheld and battery powered for field use
