HEAT INSULATION Features: Small and light Lithium ion battery with ultra fast charge CATIV 600V rated Mains / line operation even with totally dead battery Tough dual case construction Fully specified guard terminal performance High 3mA noise immunity Dedicated AC/DC voltage range with frequency (Hz) measurement Date and time stamped test results User settable test voltage preset Measures up to 20 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 Offering CAT IV, the Megger MIT1025 10-kV Insulation Resistance Tester is compact, light 10 kV insulation resistance tester for the diagnostic testing and maintenance of high voltage electrical equipment. Enclosed in a tough case it is both smaller and lighter than its predecessor making it even easier to carry and store. As well as measuring insulation resitance to 20 TΩ, the Megger MIT525 5-kV Insulation Resistance Tester 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.
