Megger MJ159 / MJ359 Analogue Insulation Resistance Tester - Hand Cranked
NB: Quoted price will be for one unit - Please specify model choice
100/250/500/1000 V with 5kΩ range, reads to 20GΩ
These units come with excellent test voltage regulation, direct measurement readout and an external guard terminal to eliminate surface leakage current from the measurement. Two models are available for general purpose testing which include a low-voltage model.
Megger MJ159 / MJ359 Key Features:
- No scale multipliers
- Multiple test voltages for spot and step voltage testing
- Guard terminal to eliminate surface leakage current
Megger MJ159 / MJ359 Application:
These have been designed for convenience and ease-of-use when testing complex or larger electrical installations, and commissioning, servicing or maintaining electrical equipment. They are designed for the safe testing of motors, generators. cables, switch-gear, transformers, distribution networks, industrial and domestic installations, components and appliances.
What‘s the difference between the MJ159 and the MJ359?
The difference is the type of power source:
- MJ159 is derived from a low-voltage, hand cranked generator which has been designed to be easy to turn even under full load conditions. The low-voltage
generator is connected to an electronic inverter to provide a very stable test voltage. Accuracy of measurement is unaffected by
variations in the generator cranking speed and the test voltage is maintained at its rated value.
- MJ359 is provided by 120 V ac 50/60 Hz or low-voltage generator.
