KEW 4106 KYORITSU 4 Wire Digital Earth Testers

Details of KEW 4106 KYORITSU Earth Resistance Tester (4 Wire Digital Earth Testers)

The KEW 4106 KYORITSU Earth Resistance Tester (4 Wire Digital Earth Testers) measures 167x185x89 mm and weighs only 900 grams, making it easy to carry due to its compact size and light weight. It can measure earth resistance using 2, 3, or 4 wires within the same device, with an intuitive knob interface for ease of use and a clear display.

• Measures earth resistance and soil resistivity in 2 / 3 / 4 wire modes within the same unit
• Automatically selects test current frequency (Test Current Frequency) at 94 / 105 / 111 / 128Hz
• Uses Fast Fourier Transform to reduce noise signals for stable measurements
• Can store up to 800 measurement results in memory
• Generate reports via USB port using the included "KEW Report" software
• Suitable for soil surveys during design and installation of grounding systems
• Helps avoid additional costs for new ground installations
