HTC Instrument Digital Earth Resistance Tester – Professional 3-Terminal Soil Resistivity & Grounding Tester with Large LCD, Data Hold, and Rugged Carrying Case

Product Description The HTC Digital Earth Resistance Tester is a high-precision instrument designed for evaluating the safety and efficiency of grounding systems. Crucial for industrial electrical installations, telecommunications towers, and lightning protection systems, this device measures the resistance of the earth electrode and soil resistivity. Unlike standard multimeters, it uses a specialized three-terminal (Fall-of-Potential) method to ensure highly accurate readings. Its rugged, double-insulated housing is built to withstand harsh field conditions, making it an essential tool for the electrical auditing services at Robogears Pvt Ltd.

Key Highlights

• Three-Terminal Precision: Utilizes the standard E (Earth), P (Potential), and C (Current) probe setup to eliminate lead resistance errors and provide professional-grade results.

• Large Backlit LCD: Features a 3½ digit display that is easy to read in direct sunlight or dark industrial basements, complete with a low-battery indicator.

• Response Time & Stability: Engineered with advanced filtering to prevent interference from stray earth currents and local AC noise, ensuring a stable reading within seconds.

• Data Hold & Zero Adjustment: Allows the user to "freeze" a measurement on the screen for easy documentation in your Odoo ERP system.

• Comprehensive Kit: Typically comes with high-quality auxiliary earth spikes, heavy-duty lead wires (Green, Yellow, Red), and a shock-resistant carrying case.
