ACME - Model CO2-2000 Series -Carbon Dioxide Monitor
This state-of-the-art instrument measures Carbon Dioxide (CO2) concentrations in the parts per million (ppm) range and is ideal for applications ranging from conference rooms to cafeterias. The CO2-2000 is easy to install and support. Measurement output is via a 4 – 20mA current loop or a 0-10V interface. A completely isolated power supply eliminates any ground loop or electrical interaction problems when multiple units are connected to the same controller. Low power consumption makes the CO2-2000 perfect for battery-operated or other power-sensitive applications. The CO2-2000’s single gas verification makes field calibration a snap, and its superior design means significantly longer calibration intervals.

The CO2-2000’s versatility is enhanced by options to satisfy most applications. The clear, bright 0.4″ high LCD display option is readable from any angle for installations where local annunciation of the CO2 concentration is desired. For direct control applications, the relay option can be configured to open or close above the setpoint and is easily adjusted in the field. For plenum sampling requirements, the popular duct option is easy to install.
