MTP 5637 Clamp-On Ground Resistance Tester

The MTP 5637 advances the usability of clamp-on ground testing.
The larger jaw opening allows tests on a wider variety of ground rods and installations. Auto-Detects if jaw is open or if there is ground noise.

Comes complete in hard sided carry case and calibration loop is included.

Othe features include:

• Non-Contact Ground Resistance Measurement
• No Auxiliary Electrode Needed
• Jaw Diameter 35 mm
