Comprising four 4-terminal testers with output voltage of 25 or 50 V, DET4 Series tests earth/ground resistance as well as soil resistivity. DET4TC2 and DET4TCR2, featuring ART attached rod technique capability as well as stakeless testing, measure resistance up to 200,000 Ω, while DET4TD2 and DET4TR2 measure resistance up to 20,000 Ω. All are IP54-rated with built-in voltmeter and large selector switch that enables user to choose 2, 3, or 4 pole tests, even when wearing work gloves.
