- Flexible fiber optics light guide versions - with optional laser targeting system to define target spot.
- High level linear output.
Radiation ThermometersProven, reliable electronics and a high quality optical system combine to give a thermometer which delivers accurate, dependable temperature measurement. A rugged die-cast aluminum body, with a high quality electrical connector, ensures reliable performance. Standard bodied thermometers all feature through-the-lens sighting with a 6° field of view. Adjustable focus with a circular graticule gives precise alignment on to the smallest of targets. Two optical variants are available: Standard focus - adjustable between 500mm and infinity, and Short-focus - viewing from 350mm to 1m. Close-up lenses are also available which can measure targets as small as 0.45mm from as close as 90mm. Fiberoptic Thermometers The use of flexible fiber optics light guides allows the detector and electronics enclosure to be located in a less hostile environment, and enables access to difficult targets. The fiberoptic thermometers are available with an optional integral laser targeting system which defines the target spot for accurate alignment. The use of fiber optics permits viewing of normally inaccessible targets, where there are high magnetic fields or in high ambient temperatures up to 200 °C without cooling of the optic head. There is a choice of three optic heads and three light guide lengths. Emissivity EnhancerThe Emissivity Enhancer improves the accuracy of System 4 short wavelength thermometers on difficult to measure materials such as bright annealed and stainless steel strip. Intended for use on low emissivity materials it gives enhanced emissivity values.
