The OS66 Series of non-contact infrared thermometers extends OMEGA’s OS65 Series shown on preceding
pages. The difference: OS66 Series is designed for higher temperature applications, with accurate results in the
800 to 1500°C (1500 to 3000°F) range.
The OS66 Series includes an infrared sensing head, signal processor module and detachable 4.6 m (15')
interconnecting cable. The OS66 Series works with the same accessories as the OS65 Series.
