MIT525
5 KV DIAGNOSTIC INSULATION RESISTANCE TESTER
Megger’s new range of d.c. insulation testers, MIT525 are targeted at original equipment manufacturers and industrial companies. MIT525 have a full suite of test modes as well as on-board memory and the ability to stream data / download data to a PC / laptop. Instrument productivity is a focus of the new MIT range, which offers rapid charge batteries and operation from an a.c. source if the batteries are flat. Rapid charge batteries enable > 60 minutes testing after a 30 minute charge.
- 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.

Other Products
TOR-1
Transformer Oil Express Test Kit TOR detects moisture in oil quickly and precisely – even in miniscule quantities.
Express test kits have been developed specifically to detect the amount of moisture in dielectric insulation oils, which is necessary for normal operation and timely maintenance of electric equipment. The high precision and excellent long-term stability make this testing device an ideal solution for continuous monitoring of moisture in transformer oils.
The test kit is compact, reliable, simple to operate and multifunctional; it is the best choice for moisture measurement. The device also measures such parameters as water activity (aw), temperature (t), and calculates absolute water content in ppm. The device combines everything necessary for simple and comfortable operation: two digital displays to indicate sample temperature moisture content in ppm, a detachable sample container and two buttons: power and measurement.
TOR-80
The TOR-80 unit is designed to determine the electric breakdown voltage of transformer oil and other liquid dielectrics in accordance with IEC 60156, ASTM D877, ASTM
D1816, GOST 6581. It is a fully automatic device that allows testing to be performed according to the procedures specifed in these standards, as well as user procedures specifed in the
appropriate section of the setup menu.
GUIDE PS400
The Guide PS Series high-performance thermal camera is designed to make the inspection, maintenance and troubleshooting work easier, faster and more accurate.
