Description
The Ground Continuity Tester from Prism Test & Measure Pvt. Ltd. is designed for accurate measurement of very low resistance in grounding and bonding circuits. It is widely used in electrical safety testing, equipment grounding verification, and quality control applications.
The instrument applies a constant AC test current and measures the voltage drop across the resistance, ensuring reliable measurement of grounding continuity. It is suitable for laboratories, production testing, and electrical safety compliance testing.
Key Features
• digital voltmeter indication for clear voltage monitoring
• programmable timer to set test duration
• test ON operation through toggle switch
