Inspect the 'uninspectable'.

The products are large format infrared and visual inspection windows that allow a complete visual and infrared scan of busbar joints under load and also act as access ports for repairs.

Another new development is the option to include temperature measurement within the PESD product.  This allows the difference between ambient and the temperature inside the cabinet to be measured – also known as Delta T.  

IRISS manufactures industrial grade polymer windows for infrared inspection. IRISS Platinum, for example, is an infrared window that allows inspection in ultraviolet, visual and all three infrared spectrums. It can be supplied in any shape or size.
