UNI-T DIGITAL EARTH TESTER
- UT520 series earth resistance tester has the functions of backlight display, low battery display, data hold, data storage, auto power off and power saving. It can not only be used for accurate three-wire measurement but also simple two-wire measurement.It is applicable to measuring the earth resistance of all kinds of electrical power system, electrical equipment and anti-thunder equipment. It can also measure the earth voltage.
- Earth resistance testing can be performed across three ranges: 0-20Ω (with accuracy of ±(2%+10), 0-200Ω (±2%+3) and 0-2000Ω (±2%+3).
- It is used to measure whether items that should be connected to the earthing system are effectively bonded, and can quickly identify such problems as corroded connections, loose bolts, inadvertent connections or separations.
