UT278A + Clamp Earth Ground Testers Product ID: UT278A+
A poor grounding system will affect the safety of people and equipment.
What is well-grounded?
The leakage conductive part of the equipment should be well connected to the ground. The grounding resistance should be as small as possible relative to the connection impedance between the device and the ground.

The hook-type grounding resistance meter is a non-contact measurement method, the measurement time is only 1/10 of the traditional method, no traditional auxiliary electrode rods are required, and no wire trimming is required. Measurable resistance: 0.1 – 1200Ω. UT278A clamp-type grounding resistance The meter can also measure leakage current and neutral current in grounded systems. UT270 series clamp earth resistance tester is widely used in earth resistance measurement and loop resistance measurement of electric power, telecommunication, meteorology, oil field, construction, and industrial electrical equipment.
