GTECH - DIGITAL INSULATION TESTER (GTECH-9550) +FREE CALIBRATION CERTIFICATE

The G-Tech 9550 Digital Insulation Tester is a handheld insulation resistance tester used to assess the health and integrity of electrical insulation in cables, motors, transformers, switchboards, and other electrical equipment. It applies a high DC test voltage and measures leakage current to determine insulation quality — crucial for ensuring safety, preventing breakdowns, and reducing electrical hazards.

📊 Key Features

• Supports test voltages up to 5000 V DC, making it suitable for medium- to high-voltage insulation testing used in industrial and utility environments.
• Measures insulation resistance typically from 1 MΩ up to around 200 GΩ, covering a broad span of insulation conditions from low to very high.
• Digital LCD display (typically ~1999 counts) shows insulation resistance readings and test status clearly, aiding fast interpretation.
• Features automatic range selection, simplifying operation by automatically choosing the appropriate range for measured values.
• Data Hold helps freeze readings on the display for easier recording.
• Backlight/LV indication improves visibility in dim lighting and alerts when high test voltages are present.
• Low battery indicator ensures you know when replacement is needed.
• Designed with protective circuitry and overload protection to help safeguard against misuse.
• Often supplied with test leads, batteries, and a hard carrying case for field use.
