Metrel MI 3121 SMARTEC Insulation Continuity Tester

The MI 3121 SMARTEC Insulation / Continuity is a new generation 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. FEATURES Large LCD display with bargraph and backlight. High measuring range of up to 30 GΩ with test voltage from 50 V to 1000 V. Fast and reliable continuity tests with automatic polarity reversal. Voltage and frequency measurements. Pre-programmed limits. PASS/FAIL evaluation of measurement result. Bright GREEN/RED indicators provides visual evaluation of results. Suited for testing on CAT IV installations. Magnetic holder allowes hands-free operation. Built-in battery charger. Two level memory structure for saving of test results and parameters. Basic downloading with EuroLink PRO PC SW package. Compatible with EuroLink PRO Plus PC SW package. USB and RS232 ports.
