• Measures up to 10 TΩ
• PI, DAR, DD, SV and ramp test
• Improved productivity – operate from line power/mains if battery dead
• Li ion battery - extended capacity, rapid charge
• Advanced memory with time/date stamp
• CATIV 600 V safety rating

Offering CAT IV, the MIT525 is compact, light 5 kV insulation resistance tester for the diagnostic testing and maintenance of high voltage electrical equipment. It is both smaller and lighter than its predecessor, making it even easier to carry and store.

As well as measuring insulation resistance to 10 TΩ, the MIT525 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.

Product Highlights

Smaller size and lighter weight allows easier transport and use without compromising performance.

High measurement range enables installation testing and long-term trending of higher value apparatus.

Unique dual case design allows for fire-retardant protection while maintaining ruggedness.

High-quality, flexible silicon test leads meet safety regulations of IEC 61010-31:2008 while ensuring measurement accuracy.

Timed IR plus PI, DAR, DD, SV and ramp tests maximize diagnostic testing capability.

Operate from line power when battery fully discharged (charges while operating).

Two and one-half hour full battery charge time (one half hour charge for one hour testing) significantly increases productivity.

Up to six hours continuous testing (5 kV) on a single battery charge.

Industry best guard terminal performance to insure highest accuracy of measured values.

Enhanced driver technology provides plug-and-play when connected to the internet. No tedious and potentially interruptive setup procedures.

Dedicated voltmeter function (30 V to 660 V) with frequency measurement allows the user to check for induced voltages.

CATIV 600 V safety rating on all terminals allows for safe use in the widest range of applications.

Large LCD with automatic backlight.

Noise filter rejects up to 3 mA noise for effective operation in electrically noisy environments.

High altitude operation up to 3000 m while maintaining CATIV 600 V rating.

Rotary switch operation for easy, intuitive field use.

Field replaceable battery
