A traditional British electrical testing instrument designed for measuring insulation resistance in electrical installations, wiring and equipment.
Features a 500V insulation testing function, analogue meter display and robust portable construction.
The instrument appears to be in good overall cosmetic condition for its age, with general signs of previous use and storage.
No test leads are included, so it has not been possible to carry out any electrical testing. Its functionality and calibration have therefore not been verified.
The instrument is believed to be in working order, I will therefore offer a 2 week warranty to allow time for testing
An interesting piece of vintage British electrical engineering equipment, suitable for collectors, restoration enthusiasts or electricians familiar with older testing instruments.
Due to its age, professional inspection and calibration are recommended before any practical electrical testing.
Please study all photographs carefully for condition and specification.
