*Important Calibration Information:
This instrument comes complete with the manufacturer’s calibration certificate. Please be aware that these certificates are generic and may also be time lapsed. If you would prefer a personalised full traceable calibration certificate applied to the equipment before dispatch, then please select this option from the drop-down menu above, an additional calibration charge will apply.
The MIT300 series has applications in all aspects of domestic, commercial and industrial electrical contracting, building maintenance, testing, inspection
and servicing. Combining both Insulation testing and continuity testing, each instrument caters for all aspects of fixed wiring installations.
Further applications can be found in panel building, testing of motors, generators, switchgear and power tools, street lighting and low volume
manufacturing environments etc.
All the MIT300 (except MIT310A) range is supplied with a warranty upgradable free to a full 3 years.
