Reviewing of UNI T UT18C Auto Range Voltage Meter Continuity RCD Tester LED Detector

Reviewing of UNI-T UT18C 0~690V AC DC Voltage Testers LCD Display Auto Range IP65 Waterproof Meter No Power Test Function UPDATED 2021 Reviewing of UNI-T UT18C Auto Range Voltage Meter Continuity RCD Tester LED Detector UT18 series are designed for testing AC/DC voltage, 3-phase voltage, phase sequence, continuity, and more. This series is categorized as CAT IV 600V and meets IP65 standard. These voltage testers are perfect tools for electricians to quickly measure voltage levels in all environments. This series should NOT be used with 110V electrical systems. Features 1. Auto power off, the conductor to be measured is greater than 12V 2. Phase rotation test 3. Continuity test with buzzer and LED indication 4. RCD: Detecting leakage protective switch 5. Low battery Indication and over-voltage prompt 6. LED prompt 7. Flashlight 8. Test live voltage without batteries 9. Buzzer and silent mode 10. Auto standby mode 11. Auto range/Inspection 12. Voltage, frequency display 13. Data hold 14.
