• Measures up to 30 TΩ
• PI, DAR, DD, SV, and ramp test
• Improved productivity – can be operated from mains power if battery dead
• Li-ion battery - extended capacity, rapid charge
• Advanced memory with time/date stamp
• CAT IV 600 V safety rating

The MIT1525 15 kV diagnostic insulation resistance tester is a CAT IV rated, compact tester for the diagnostic testing and maintenance of high voltage electrical equipment. This top-of-the range instrument is enclosed in a tough, dual case, it is both smaller and lighter than its predecessor making it even easier to carry and store.

As well as measuring insulation resistance to 30 TΩ, the MIT1525 also offers various diagnostic tests such as polarisation index, dielectric absorption ratio, step voltage, dielectric discharge, and ramp testing.

Now equipped with lithium-ion fast rechargeable batteries, the instrument has a large, clear, easy-to-read, display making it equally suitable for use in both bright sunlight and poorly lit environments. Information displayed includes resistance, voltage, leakage current, capacitance, battery status, and time constant. In addition, the elapsed time of the test is displayed constantly, removing the need for separate timer.
