NIR Borescope 2K

A high-resolution short-wavelength radiometric infrared borescope imaging camera designed for a wide range of continuous process monitoring and control applications.


Designed specifically to produce high-definition thermal images in a temperature range from 600 to 1800°C (1112 to 3272°F), the NIR-Borescope-2K (NIR-B-2K) delivers continuous process monitoring and control for large furnaces.

A radiometric infrared borescope camera, it provides a cutting-edge thermal image with an outstanding definition of 3 million pixels (1968 x 1472), unaffected by the hot atmosphere and gases of the furnace.

The NIR-B-2K allows operators to measure from any of three full radiometric-calibrated mega pixels, providing data to optimise furnace temperature. This helps to save energy, increase efficiency and reduce emissions.

With continuous coverage via Gigabit Ethernet connection and automated alarm outputs, the NIR-B-2K is ideal for use in rotary furnacesreformer tube furnacescoal fired power boilersglass melt furnacescement kilns and biomass boilers.

Needing only a narrow opening in the furnace wall, the NIR-B-2K’s wide-angle lens provides a 95° horizontal field of view. This ensures an extensive measurement area covering stock, refractories and burner/heating zones in a single thermal image.

The NIR-B-2K uses advanced spectral filtering, unaffected by furnace temperature and gases, to deliver real temperature readings and clear monitoring of the interior. Patented background compensation corrects for background reflection, enabling continuous, correct stock temperature readings.

An auto-retract system safeguards the thermal imager against damage from overheating in the event of a loss of water flow, air pressure or electricity supply, or if a borescope tip high-temperature alarm is activated. Electric version available.

The NIR-B-2K is AMETEK Land’s high-definition thermal imaging solution for temperature monitoring in furnaces, refractory areas and of stock.
