Overview
Enviro Test Construct’s Industrial Earth Ground Resistance & Leakage Clamp Meter is fast and safe. This device measures indoor/outdoor earth-ground resistance and ac leakage currents without disconnecting the earth-ground stake from the grounding system. In addition, this clamp meter features a heavy-duty clamp jaw that stays in alignment and calibration in industrial conditions.
Features
- AC Leakage Current Measurement: Identify leakage without disconnecting the earth ground stake.
- Rugged Design: Heavy-duty clamp jaw maintains alignment and calibration in industrial environments.
- Data Logging: Automatically records and stores up to 32,760 measurements at pre-set intervals.
- Alarm Threshold: User-defined high/low limits for fast measurement evaluation.
- Band-Pass Filter: Selectable function for optimized measurements.
