Megger's DET4TD2 Earth Tester is an upgraded instrument with a multitude of settings that can perform 2, 3, and 4 point testing with a selectable 25V or 50V output. Thanks to its IP54 rated dust and water-resistant design, the Megger DET4TD2 is perfect for usage both indoors and outdoors. Its large rotary dial and test button make it simple to select tests with this instrument. The instrument also has a button on the front that allows you to switch between 25 and 50V modes. The DET4TD2 can accurately detect ground voltage thanks to its integrated voltmeter, as well as automatically assessing and reporting the connection and status of any attached P and C spikes. The results are displayed on the built-in LCD screen. Along with measuring resistance from 0.01Ω to 20kΩ (with a resistance accuracy of 2% ±3 digits), this instrument can also measure earth voltages up to 100V. The Megger DET4TD2, which comes with a calibration certificate and a sturdy travel case for added security, is an ideal earth tester for a range of applications.
