What our customers say…

When rebuilding one of our clamshell furnaces we opted for four Impac ISR 6 pyrometers for precise temperature measurement. I am very impressed with the quality of every component from the cooling jackets to the sensors themselves, which seem exceptionally well made. I would not hesitate to contact LIMAB in the future for any other applications that I may need help/equipment for.

John Parkin – Senior Site Electrical and Control Engineer
When we needed to measure the temperature of an ion source within a high vacuum, we chose to use an Impac pyrometer from LIMAB. The advice given by the Technical Sales Manager meant that the equipment was easily integrated into our system and immediately provided us with very impressive results.
