ETCR 2100+ clamp ground resistance tester with 32mm jaw and digital display

ETCR

ETCR 2100+ Clamp Earth Ground Resistance Tester 0.01-1200 Ω 32mm clamp 99 records

SKU CH-QH2Y-1GXYW

Measures loop grounding resistance from 0.01 to 1200 Ω with a 32 mm clamp and stores 99 records without disconnecting leads

  • Measures loop resistance without disconnecting leads or auxiliary electrodes
  • Wide 0.01–1200 Ω range with 0.001 Ω resolution for detailed readings
  • 32 mm clamp jaw fits a variety of conductor sizes
  • Stores up to 99 records for later review and reporting
  • Detects ground faults that traditional methods cannot identify

Ground loop tester for industrial sites

The ETCR 2100+ clamp meter measures earth ground resistance from 0.010 to 1200 Ω without disconnecting grounding leads or driving auxiliary electrodes. Its 32 mm jaw fits conductors in power substations, telecom towers, meteorology stations, oilfields and general industrial equipment. The instrument calculates loop resistance using the R=E/I principle, capturing combined grounding-body and lead resistance in a single step.

On-board storage and alarm system

Up to 99 measurement records are stored internally for later review. Audible and visual alarms activate when interference signals are detected, while an upgraded relay self-test with advanced algorithms verifies instrument integrity at power-up. The six-button panel and instant start-up reduce setup time during routine inspections.

Suited for loop-system maintenance teams

Technicians who regularly test multi-point grounding grids in live installations will benefit from the clamp-on method and data logging. Buyers who need to verify isolated single-point electrodes or require certification to a specific standard not mentioned in the manual should look at alternative instruments.

Questions about this item

How often do the 32 mm clamp jaws need calibration or replacement?

The 32 mm clamp jaws are a fixed part of the ETCR2100+; no user-replaceable jaw inserts are described, so only periodic calibration of the complete tester is required.

What measurement limit is reached first when testing continuously — the 99-record memory or the 1200 Ω upper range?

The 99-record data storage fills first; once 99 readings are saved, older entries must be cleared before new loop-resistance values up to 1200 Ω can be stored.

How much heat or noise does the ETCR2100+ produce during all-day loop-resistance testing?

Low power consumption and instant start-up keep heat minimal; only the audible beep-beep-beep alarm sounds when interference or threshold limits are detected.
