term adjustment) signal processing technology to

deliver industry leading long-term accuracy and

reliability.

Standard features include a field selectable output

signal of either 4-20 mA, 0-5 Vdc or 0-10 Vdc

for the highest versatility, programmable CO2

measurement span, a backlit alpha-numeric LCD

and easy menu operation for configuration.

Optional features include a resistive temperature

sensor output and a control relay with

programmable setpoint,hysteresis and time delay.
