mastech ms7222 rtd resistance temperature detector calibrator measuring
Earth resistance clamp is a breakthrough from traditional tester. Neither the supplementary earth leads nor the break earth equipment is necessary. Ground resistance result can be get safe and fast only by clamping the ground line. Additionally current testing is also provided. High sensitivity clamp meter can measure the leakage current to 1mA neutral current to 20A RMS. It is especially important for testing ground circuit with strong interference and ripple that will influence the electrical quality. Besides industrial electronic equipment. It is also widely used in the field of electric power distribution telecommunication and architectural ground. Product Feature: 0.01 high accuracy for low resistance measurement; 0.001 high resolution; Record 99 resistance measurement values; Set alarm threshold in 1 to 100; Measure leakage current and neutral current; 45mm x 32mm large jaws of exactitude measurement probe; With indication of the batteries capacity; Digital measurement auto range easy operation; Double insulation strengthen the interference resistance; Untouched measurement ensures the safety; One second per test imply the quick measurement; Display: LCD 3 3/4 digits
