The GT400HDXL or GT400HDXLVMA provide quality testing for personal protective grounding assemblies. The GT Series Grounding Assembly Testers are designed to provide integrity testing of the electrical characteristics of portable protective grounding assemblies. The GT Series Testers provide a reliable test by administering Rated ASTM Current up to 400 Amps through the grounding assembly and measuring the voltage drop across the assembly. The voltage drop in conjunction with a thorough visual inspection determines if the grounding assembly meets ASTM electrical specifications.

The GT Series Testers are housed in a sturdy carrying case. Each unit is compact, weighs approximately 60 pounds and quickly confirms the condition of an entire grounding jumper assembly. It is easy to operate and can be set up for testing in a matter of minutes by qualified lab or field personnel.
