The OS37-CF/OS37-60CF Model infrared thermocouples
for high-emissivity targets (non-metals and coated
metals) and the OS38-CF/OS38-60CF Model for
low-emissivity targets (clean metals) feature an internal
screw that adjusts the 2% accuracy band anywhere
within the overall temperature range. All of these
units use a lens to produce a minimum spot at a focal
point. Models with 30° optics produce a rectangular
minimum spot size in the focal plane by using a masked
detector. Models with 1° (60:1) optics produce a more
conventional round minimum spot size at a focal point.
All models feature a built-in air purge.

The OS37 Model infrared
thermocouples for high-emissivity
targets (non-metals and coated
metals) and OS38 Model lowemissivity units (clean metals)
feature an internal screw that
adjusts the 2% accuracy band
anywhere within the overall
temperature range. Both series
are available in 10:1, 20:1, or
100:1 optics. All models have
a built-in air purge collar that
conveniently and efficiently
maintains optical cleanliness in
harsh environments.
