With 0–200 ppm range and 5,000–7,000 ft² typ coverage area, Model CMT200 provides field-selectable current or voltage output that is proportional to gas concentration. Electrochemical sensor is field replaceable and provides readings accurate to ±2% of reading for up to 4 years with proper calibration. Field calibration can be accomplished using Model GCK-200CO-2000CO2 calibration gas, Model A-507A calibration adapter, as well as onboard span and zero potentiometers.
