*Important Calibration Information:
This instrument comes with a ‘manufacturer's certificate of conformity’. It is important to understand that this does NOT constitute a ‘traceable calibration certificate’. A certificate of conformity merely states that the equipment has been designed and produced to meet the requirements of its intended application.
Where calibration of an instrument is possible, we will offer this as a separately purchasable item and may be selected from the drop-down box above. You will be sent a full traceable calibration certificate produced in our laboratory and applied with your details as required.
The new range of insulation resistance testers (IRTs) are smaller and lighter than previous models yet offer advanced features and rapid charge capability. The range consists of three models; an entry level 5 kV and two fully featured units, one 5 kV the other 10 kV. Resistance measurement up to 10 TΩ for the 5 kV models and 20 TΩ for the 10 kV model.
The Insulation Resistance (IR) test is a qualitative test that indicates the effectiveness of a product’s electrical insulation. Applications include cables, transformers, motors/generators, circuit breakers and bushings. The IR test is ideal for measuring and recording long term stability of insulation over time, a process known as trending. IR tests are temperature dependent and require adjustment to a reference temperature. Storage models offer a temperature recording option.
