ATEX, IECEx and CSA HAZARDOUS AREA CERTIFIED The NIR Borescope (NIR-B) 3XR is a short wavelength radiometric infrared borescope imaging camera for steam reformer and cracker tube continuous temperature measurement and furnace optimisation and monitoring. ATEX and IECEx approved to Ex nA IIC T4 Gc for use in Zone 2 gas atmospheres and CSA Certified for US and Canada to Class I, Division 2, Groups A, B, C, D T4, the NIR-B 3XR provides a high resolution thermal image with real time continuous high accuracy temperature measurements of both the tube wall and refractory wall surface. The camera measures temperatures in the single range 600 to 1800 C (1112 to 3272 F) and utilising the latest wide dynamic range imaging technology. This is ideal for applications with a high differential temperature in the field of view such as tube and furnace walls. Find out more about the new NIR-B 3XR.
