Offering both superlative performance and exceptional
value, the OMEGA®180A Series temperature recorders
can be easily incorporated into most process monitoring
applications. Continuous recording models are available
with 1, 2, or 3 channels; they include high quality
sapphire tipped pens for long life. A six-speed chart
drive [12.5, 25, 75,150, 375, 750 mm/hr (1 mm =
0.03937 in)] is standard on all recorders and is switch
selectable, eliminating the need to change gears. The
multipoint models have either 6 or 12 channels and
utilize a unique color dot print method for extremely
legible recording. All model 180A recorders accept
thermocouple types J, K, T, E, and R. A 0 to 100 mV
range is also available, expanding the recording
capabilities to other process sensors. Cold junction
compensation and linearized electronics are standard
on all models. Sensors are easily connected via screw
terminals provided at the back of the instrument. Other
standard features include an illuminated chart and
a protective glass door.
