Description
Megger MJ159 Hand-Crank Analog Insulation Tester (1kV)
The Megger MJ159 is a classic, high-reliability analog insulation tester engineered to deliver elite operational performance without the need for external power sources. By addressing the requirement for field-ready metrology, this hand-cranked instrument generates test voltages up to 1000 VDC, effectively minimizing measurement uncertainty in remote locations through a direct-reading analog meter that requires no multipliers. The metrological architecture of the MJ159 ensures absolute traceability across an insulation resistance range of 0 to 2000 MΩ, providing technicians with high-trust results for the verification of motors, transformers, and cable integrity.
Built for industrial longevity, the MJ159 is housed in a rugged enclosure measuring 7 x 6 x 5 inches and weighing only 4.5 lbs, ensuring ease of transport for field audits. Its technical sophistication is centered on its dual-functionality, allowing for the measurement of AC line stimulus up to 600V in addition to primary insulation testing. As a professional-grade metrology tool, this hand-cranked Megger unit is supplied complete with test leads and a protective carrying case, standing as a time-tested solution for technicians requiring surgical precision in electrical safety testing where battery maintenance is impractical.
