      	| OMEGA's OS550A Series (Upgrade
from OS550 Series) industrial, high performance,
economical thermometer/transmitter offers a
wide choice of temperature ranges,
optical fields of view and 3 analog
outputs (1 mV/degree, 4 to 20 mA,
and 0 to 5 Vdc) to feed directly into
panel meters, recorders,
temperature/process controllers,
data loggers, data acquisition
systems, or other process
instrumentation.
 
 Since the OS550A Series infrared
thermometers do not use chopper
motors or vibrator mechanisms,
they can be mounted in any position
and in hostile environments without
suffering any loss in performance.
