The OS950 Series has been discontinued. Please contact our Temperature Engineering department for possible alternative.

OS950 Series Infrared Scanners from OMEGA provide the highest accuracy available anywhere!

The OS950 Series is an entirely different type of instrument than conventional temperature measuring devices. Designed specifically for the highest possible accuracy, it is the only infrared instrument which can be certified with NIST-traceable accuracy on real surfaces of unknown emissivity, while remaining completely free the contact errors and heat errors of contact devices.

Temperature Range:
    OS951/2: -45 to 287°C (-50 to 550°F)
    OS953/4: -18 to 540°C (0 to 1000°F)
    OS955: 86 to 653°C (186 to 1207°F)
    OS956: 86 to 871°C (186 to 1600°F)
Emissivity Adjustment: Automatic emissivity compensation system (best for emissivity above 0.8)
Linearity Error (% of Reading):
    OS951/2: 1%
