Digital Multimeter Electrical Test Kit, Non-Contact Voltage Tester, Receptacle Tester, Carrying Case and Batteries
The MM320KIT Digital Multimeter Electrical Test Kit from Klein Tools is designed with reliability and safety in mind. This comprehensive kit comes with MM320 Digital Multimeter, NCVT-3P Non-Contact Voltage Tester with Flashlight, ET45 Voltage Tester, RT210 GFCI Receptacle Tester, a padded storage pouch and all required batteries. All offered in one kit for value and convenience.
- Digital Multimeter measures up to 600V AC/DC voltage, 10A DC current and 2 ohm resistance
- Meter also test batteries, diodes, and continuity
- Voltage Tester NCVT-3P has dual-range capabilities to detect from 12 to 1000 V AC or 70 to 1000V AC for a broad variety of low-voltage or standard voltage applications
- Bright flashlight illuminates work area and may be used independent of NCVT-3P voltage detection function
- ET45 tests AC voltages from 28V to 240V AC at four useful levels aligned with commonly used residential voltages, and DC voltages from 32V to 330V at four common levels.
- Built in test lead holder on back: ET45 holds leads in 1 of 2 positions one so they are spaced correctly to test tamper-resistant US-style outlets, the other for convenient storage of the test leads
- RT210 detects the most common wiring problems in standard and GFCI receptacles including open ground, reverse polarity, open hot, open neutral and hot/ground reversed
- Receptacle tester works on GFCI outlets and confirms operation of the ground fault protective device
