| With a combination
of powerful features, the new portable and rugged OS520 series infrared
thermometers offer solutions for many non-contact temperature measurement
applications. Emissivity adjustable in 0.01 increments, provides versatility
when measuring a variety of surfaces. A custom backlit LCD display provides
dual digital display of both current and max or min temperatures simultaneously.
This provides the user with more information at a glance. The OS520 also
features a high alarm setpoint, providing both audible and visual indication
of the alarm status. The standard 1 mV per degree analog output allows
interfacing with data acquisition equipment, including chart recorders,
dataloggers and computers.
