Ground Continuity Testing

Available with IEC/ISO 17025 Certificate of Calibration
Automated Digital Ground Continuity Testers, models GC1000, GC2000, and GC3000
Part of ED&D's leading-edge "Millennium Series" line of electrical safety testers
Makes your job easy and safe!

These are the world's fastest, easiest, and most affordable Automated digital Ground Continuity testers. Simply put, the Millennium Series Ground Continuity testers from ED&D makes all others obsolete. This is the only such tester available produced by experts in Product Safety! We make these at our facility in the USA, they are hand-assembled using the most robust parts and wiring available - - our goal being to offer superior craftsmanship throughout our extensive product line.

Product Details

  • 1 Button Testing - No setup required, just plug right in!
  • Digital LED display reads out in Ohms
  • Also performs the Low Current Ground Continuity test, at the same time!
  • Auto Test Time (1 sec. / 60 sec.)+ - No need to set a timer or clock watch
  • Custom universal receptacle accepts both 120V and 240V plugs.
  • Zero feature allows you to "zero-out" the test lead impedance.
  • Meets UL, CSA, CE, EN, IEC, MIL and all other international safety agency requirements.

Note: In the standards, the 0.1 ohm limit is for the product under test's grounding system only, not including the power cord impedance. Our "zero" feature allows you to zero out the cord impedance. This ensures no false failures and extremely accurate results!

Test Current 25A or 30A (selectable) Accuracy ± 2% full scale
Input Current 1A Weight 15 lbs.
Input Frequency 50 - 60 Hz Input Voltage 100 - 120 or 220 - 240 VAC
Test Time 1 sec or 60 sec (selectable)+ Dimensions 12" x 11" x 5"
Failure Indication 0.1 ohm trip setting (0.2 ohm available)++
+ Order Model GC-1000S if you require a 2 sec. / 60 sec. test time.
++ Order Model GC-1000T if you require a .200 Ω trip limit.
