This model has an optical configuration of robust aerospace-quality, double coated Zinc Selenide lenses per Military Specification MIL-C-13508. It measures in the spectral pass band of 8 < Wavelengths < 14 Microns.

Field of Views of 2° or 15° are available. The response time of the instruments is less than 0.10 second. Emissivity is settable from 0.2 to 0.98 or can be preset at end-user’s request.

Rechargeable Nickel Cadmium batteries provide the power source. The standard output signal is RS-232C and the optional signal is analog millivolt (1.0mV/ °C).

The Model 100.3ZH is used for a variety of industrial applications where taking the temperature by any other method would be impossible due to the danger of extreme heat or where a surface is too rough or too fragile to measure in any other way.
