The top model of Metrel’s installation testers is MI 3105 EurotestXA. Features including “All-in-one” installation safety testing, AUTO SEQUENCE ® testing, integrated characteristics of fuses and RCDs (including B type), PASS / FAIL evaluation of test results, 10-level memory structure and built-in battery charger make the EurotestXA an exemplary instrument. Concentrate on your work instead on the instruction manual of your test instrument.
Additional features include TRMS current measurement, 3-wire / one clamp / two clamps earth resistance and 4-wire specific earth resistance measurements, illumination measurement and fuse / fault locator function.
All the results can be quickly saved and then downloaded via the EuroLink PRO software to the computer for evaluation and professional report generation after testing.
The MI 3105 EurotestXA performs continuity, insulation, RCD, loop, line, voltage, frequency, earth resistance and phase sequence testing required by the EN 61557 standard.
Revolutionary AUTO SEQUENCE testing and certifying safety of low voltage electrical installations.
Based on 15 years of research and field experience. Tested and recommended by specialists.
Fast: up to 5 times quicker testing.
Simple: only one single press of a TEST button guides the operator through whole procedure.
Reliable: it acquires up to 50 test results and parameters on each outlet at once. None of necessary test will be forgotten.
Automatic: it gives automatic evaluation of safety status with Pass/Fail certification of overall test results.
Standardised: it generates standardized test report in less than 1 minute.
Safe: automatically detects possible safety hazards for the operator.
