Metrel MI 3121 Insulation Continuity Tester

Regular price $ 720.00 CAD Sale

The MI 3121 SMARTEC Insulation / Continuity is a tester for dead testing of electrical installations. With both an analogue and digital representation of the results, the instrument ensures accurate measurements up to 2000 Ω on continuity and up to 30 GΩ on insulation function. Configurable limits enable a PASS / FAIL evaluation of test results, which is accompanied with the bright red and green indicator lights for comfortable use even in the dark conditions. The MI 3121 is equipped with a built-in charger and has a magnetic holder in order to free up hands for testing. All the results can be quickly saved on the instrument and then downloaded via the optional A 1291 EuroLink PRO or A 1290 EuroLink PRO Plus software for evaluation and professional report generation after testing. The MI 3121 SMARTEC Insulation / Continuity performs continuity, insulation AC voltage and frequency measurement tests.

Measuring functions

  • Insulation resistance with DC voltage;
  • Continuity of PE conductors with 200 mA test current with polarity change;
  • Continuity of PE conductors with 7 mA test current (continuous measurement) without RCD tripping;
  • TRMS voltage and frequency.

Key features

  • Insulation range: wide range of insulation test voltages from 50 V to 1000 V, measuring range up to 30 GΩ.
  • Analogue scale and digital LCD: measuring results are displayed both in numeric and analogue representation.
  • Downloadable: downloads via RS232 or USB cable directly to the PC with the help of the optional software.
  • Upgradeable: if changes occur to the regulations upgrades can be made to the firmware to keep the instrument up to date.
  • Polarity swap: automatic polarity reversal on continuity test.
  • Built-in charger & rechargeable batteries: instrument has a built-in charging circuit and comes complete with a set of rechargeable NiMH batteries.  
  • Custom limits: if limits are set on insulation or continuity function then large green and red lights of the LEDs will indicate a PASS or FAIL evaluation of test result.
  • Easy to use: large bright LCD display and large buttons enable easy handling of the instrument (even while wearing gloves).
  • Magnetic holder: magnet for fixing instrument on metal surfaces enables hands-free operation.
