Product Description
The outside CO2 transmitter device uses a highly accurate and reliable non-dispersive infrared (NDIR) sensor in a vented, weatherproof enclosure to monitor outside CO2, levels. The sensor uses dual-wavelength optics and LTA (long-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.
