EARTH RESISTANCE & RESISTIVITY TESTER - KEW 4106
The KEW 4106 Earth Resistance & Resistivity Tester is designed for accurate earth resistance measurements ranging from 0.001Ω to 200kΩ, and automatically calculates earth resistivity (ρ) using the Wenner method. This device offers automatic and manual frequency selection across four bands (94/105/111/128Hz) and provides advanced filtering to reduce noise interference. With a memory capacity of up to 800 measurements, it allows for easy data transfer to a PC via USB for further analysis using the "KEW Report" software.
Key Features:
- Wide Measuring Range: Measures earth resistance from 0.001Ω to 200kΩ and earth resistivity (ρ) from 0.1Ω·m to 1999kΩ·m.
- Earth Resistivity Measurement: Automatically calculated after setting the distance between auxiliary earth spikes (Wenner method).
- Auto and Manual Frequency Selection: Offers four frequency bands (94/105/111/128Hz) to select the most suitable frequency for earth resistance measurement.
- Advanced Noise Filtering: Uses Fast Fourier Transform (FFT) to filter out noise, ensuring stable readings even in noisy environments.
- Memory Function: Stores up to 800 measurement results, which can be easily recalled or transferred to a PC via the included USB adapter.
- Robust Design: IP54-rated protection ensures dust and drip resistance, making it suitable for field use in harsh conditions.
- Automatic Power Off: Device powers off automatically after approximately 5 minutes of inactivity, conserving battery life.
