MIT515 (5 kV), MIT525 (5 kV),  MIT1025 (10 kV) & MIT1525 (15 kV) are the newest in Megger’s line of insulation testers >1 kV. These instruments are designed based on Megger’s extensive knowledge of insulation testing (100+ years of experience) and significant feedback from actual end users. Megger has taken the best insulation testers in the world and improved them to add functionality, make them easier to use and easier to transport. They include Megger’s patented digital/analog display (real-time pointer movement), a CATIV safety rating at all terminals and a unique dual case design. 

• Industry best guard terminal accuracy
• Compact and lightweight for easy transport and use
• PI, DAR, DD, SV and ramp test
• Unique dual case design provides additional user protection
• Lithium-ion battery - extended capacity, rapid charge
• Advanced memory with time/date stamp
• CATIV 600 V safety rating on all terminals
Megger MIT515
If you need basic insulation testing, this Megger meter is suitable. It has a variable voltage of 50 Volts to 5 kiloVolts which allows it to measure resistance from 10 kΩ to 10 TΩ. 

Megger MIT525
This Megger insulation meter is similar to the MIT515 but with additional features. The MIT525 can conduct automatic Step Voltage, Ramp and Dielectric Discharge tests. It also features a real time clock and PC connectivity through USB and RS232 ports. The PC connectivity allows advanced results analysis using the PowerDB Lite software.

Megger MIT1025
The MIT1025 is like the MIT525 when it comes to features but has a higher test voltage output and a wider range of  resistance measurement

Megger MIT1525
The top of the new range MIT1525 performs insulation resistance tests up to 15 kV with a 30 TΩ maximum resistance and an accuracy of ±5 % from 1 MΩ up to 3 TΩ
