ETCR ETCR2100A+ Digital Clamp Earth Resistance Tester 0.010-1200Ω 99 Sets

Clamp Earth Resistance Tester 0.010-1200Ω

The ETCR ETCR2100A+ is a handheld digital clamp meter for measuring earth and loop resistance without driving auxiliary stakes. It is intended for electricians, maintenance engineers and facility managers who need rapid verification of grounding systems in commercial, industrial or utility environments. The instrument stores up to 99 measurement sets for later review and supports an adjustable alarm threshold between 1 and 199 Ω with audible and visible alerts when readings exceed the limit.

Jaw Opening 32 mm and CPA Type Approval

The clamp jaw accommodates conductors up to 32 mm in diameter, allowing it to fit around typical earth leads and bonding cables encountered on site. A red moulded housing protects the electronics while the six-button panel provides direct access to measurement, storage and alarm functions without menu diving. The unit carries a Certificate of Type Approval for Measuring Instruments referenced as CPA 2016E119-44, confirming compliance with the applicable metrology requirements for this class of tester.

Verify Conductor Size

Confirm that the conductors you intend to test fit within the 32 mm jaw opening; larger cables or busbars will not close the clamp correctly. Decide whether the 1-199 Ω programmable alarm range covers the pass/fail criteria required by your test procedures. The tester stores 99 data sets, so consider whether that capacity matches your logging workflow or if you need a device with greater onboard memory.
