UT18C Voltage And Continuity Tester


UT18C voltage and continuity tester is designed for testing AC/DC voltage, 3-phase voltage, phase sequence, continuity, and more. This device is categorized as CAT IV 600V and meets IP65 standard. Application fields for UT18C include smelting, electronics, manufacturing, and electrical. It is a perfect tool for electricians, to quickly measure voltage levels in any harsh environments. It should NOT be used in 110V electrical systems.

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. Polarity indication
