Metrel MI 3211 TeraOhmHP 10 kV High Voltage Insulation Tester
The MI 3211 TeraOhmHP 10 kV is a high power, portable, battery or mains powered test instrument with excellent IP protection (IP65), designed for analysing insulation resistance by using high DC test voltages of up to 10 kV. Because of its robustness (CAT IV measuring category) and high immunity to radiated EM fields, it is best suited for demanding industrial environments. Touch screen or key manipulation via menu driven LCD enables easy and transparent selection of different measurement methods and easy entry of data. Newly designed test leads have coded banana connectors for proper connection and locking to protect them against unwanted or accidental removal.
Built for the Toughest Testing Conditions
Testing in challenging environments like substations is no easy task. That‘s why you need testers designed to withstand the harshest conditions.
The Metrel MI 3211 Insulation Testers is rugged, reliable, and built for demanding environments. Electromagnetic interference, high humidity, and extreme altitudes are no match for their durable casing and colour-coded, locking test leads, which prevent accidental disconnections. For greater accuracy in high-interference environments, a shielded test lead with superior electromagnetic immunity ensures reliable results in substations and other challenging locations.
Intuitive and Familiar Operation
The MI 3211 boasts both touchscreen and keyboard operation, users can effortlessly navigate test procedures, adjust parameters, and start testing within seconds.
Safety First, Always!
Complying with IEC 61010-2-034, these testers ensure safe operation - even in burn mode. While most testing occurs in breakdown mode, burn mode is available when insulation degradation isn‘t a concern.
Precision Features for Accurate Results
Advanced features like noise rejection and test result averaging improve accuracy. Results can also be displayed in graph format and saved to the 8 GB internal memory for later analysis.
Easy Data Transfer and Reporting
Once testing is complete, results can be quickly transferred to a PC using MESM software, making report creation effortless.
