Every professional electrical worker knows the importance of proper grounding for electrical safety, and the equal importance of having the right tool for the job. The Model 309 Digital Earth Resistance Meter from BK Precision® is an accurate, affordable instrument for ensuring proper grounding, and comes with everything you need to get to work right out of the box. |
- Very high 2000 ohm resistance testing limit accommodates virtually any application without overloading
- Measures current resistance without tripping circuit breakers, minimizing downtime during recertification and other electrical testing
- Data hold function freezes the current test results on the screen for easier record keeping
- Automatically turns off output after a 3 to 5 minute continuous test to conserve battery power
- Small, lightweight, battery-powered design is much easier to manage than the large, bulky meters of the past
- Includes test leads, batteries, earth spikes, and carrying case, so there is no need to buy anything else to get started
- IEC 1010 / CAT III 200V / CE Rated
