Metrel MI3125BT Eurotest Combo Multifunction Tester (EVSE Ready)
The Metrel MI 3125BT Eurotest Combo is a handheld multifunction tester ergonomically designed to speed up installation testing and make it quick and easy.
The Metrel MI3125 BT Eurotest Combo communicates using Bluetooth with the Eurolink Android data management App. This update gives you the option to transfer test results remotely to any Bluetooth-enabled device running EuroLinkPRO Plus PC software or communicate directly with the Eurolink App.
The MI3125BT also noticeably performs a 6mA DC RCD Test, suitable for EV charge point testing. A feature often found in testers with a higher price tag.
The MI3125BT also stores and downloads test results. With its built-in memory, the MI3125BT can download data into the supplied MESM PC Software via the provided USB Lead. MESM Software can also be upgraded to MESM PRO for full 18th Edition and EVSE Test Certificates.
The MI 3125BT performs a variety of electrical tests, including: Continuity Testing, Insulation Testing, Automatic RCD testing (including 6mA for EVSE and B-type RCDs), RCD Ramp Testing with a no RCD trip feature, Earth Loop impedance testing and PSC (prospective short circuit current. Basically, all the tests you need to fully ensure safety within electrical installations in both commercial and domestic environments. The EurotestCOMBO can even perform online voltage monitoring and phase sequence testing for 3 Phase installations. The MI3125BT also carries out 2 or 3-wire Earth Spike Testing using optional kits Metrel S2026 or S2027 Earth Spike Kits.
The MI3125BT has inbuilt Fuse Characteristics tables which allow for easier evaluation of the Loop Resistance in accordance with BS EN 7671. Calculations and Tables are no longer necessary with this feature. Additional Help screens describing how to connect the instrument to the installation and how to perform the test are also inbuilt.
The ergonomic design of this instrument allows for easy operation either via the use of the supplied neck strap or hand strap. A built-in magnet helps by holding the MI3125BT directly onto metal surfaces often found around a distribution board. Two LED Indicators (green//red) are placed on both sides of the screen for clear visualisation of the Pass/Fail result, and the display is backlit for readings in dark conditions.
Below, we have included a comparison table outlining the key features of each Metrel multifunction tester model.
