Acme Engineering Products CO2-EN Series Gas Instruments

The CO2-EN carbon dioxide monitoring controller is designed to provide HVAC systems with an economical means of controlling outdoor makeup air to maintain indoor air quality and reduce heating or cooling costs in the built environment. CO2-EN is used for environmental monitoring in commercial and light industrial environments. Air samples originate from a remote sampling head that contains a high-efficiency particulate filter.,it can also be equipped with a duct-mounted sampling head for sampling return air from an office or other location (where the control unit should be hidden from view). Standard CO2-EN units are equipped with ACME’s high-capacity sampling filter assembly for remote installation from the control unit. Standard units are available with four exposure levels of 600,800,1000 and 1200 PPM CO2,allowing maximum flexibility in selecting operating levels.,the four output SPST exposure levels can also be set at the factory to any CO2 level requested by the customer. optional 4-20mA analog output signal within the sensor detection range can be used for variable drives or remote monitoring. integral or remote alarm is also available for warning at selected CO2 concentrations.
