Product Overview
The Earthing Contact Resistance Tester (ECRT) is a critical safety testing instrument designed to ensure proper earthing connections in appliances and electrical units. This test is prescribed by various safety standards and verifies the contact resistance between accessible metal parts of a device and its earth connection.
The ECRT by Sensors is designed to perform this test efficiently by passing a high current and measuring the resultant voltage drop, based on Ohm’s Law. The system’s precision-designed metering and transformers ensure highly accurate results.
Key Features:
✅ High-Precision Measurement – Accurately checks contact resistance between metal parts and earth.
✅ Heavy-Duty Cables & Crocodile Clips – Ensures minimal resistance during testing.
✅ High Current Output – Enables thorough resistance testing.
✅ Digital Meters – Provides clear voltage and current readings.
✅ Overcurrent Protection – Equipped with an overcurrent relay for safety.
✅ Customizable Current Source – Adjustable test current range to meet specific requirements.
Technical Specifications:
🔹 Power Supply: 230V / 110V AC, Single Phase
🔹 Test Voltage: 12V AC or 5V AC (as per requirement)
🔹 Test Current Range: 0 – 30A AC (customizable upon request)
🔹 Heavy-Duty Output Supply – With built-in current limiting for protection
