OS35-3-MA-250C-24V, $359, shown actual size.

The OMEGA®OS35 Series infrared temperature sensors offer intelligence in a rugged, easy-to-use package. The OS35 is centered around a high-speed microprocessor that continously monitors and adjusts the complete system. While performing the complex algorithms determining the output, it calibrates itself about once every second, removing any concerns over drift or sudden changes. Other advanced features include emissivity shift compensation and ambient radiation error correction. The rugged housing withstands thermal and mechanical shocks. The built-in air purge prevents dust, dirt, or condensing vapors from depositing on sensor optics, assuring long-term accuracy under all environmental conditions. The integral heat exchanger eliminates drift by automatically warming (or cooling) supply air to match the optical aperture temperature.
