The OS423 series are fully
functional infrared non-contact
temperature measuring devices.
Offered at an economical price, the
OS423 series offers laser sighting,
several mathematical modes, and
adjustable emissivity. Long battery
life, (typical 180 hrs without laser
or backlight), is obtained from
2 “AAA” batteries (included) along
with automatic shut-off. The
8-14 µm wavelength sensitivity
rejects spurious reflections from
local lighting.
