This state-of-the-art instrument measures Carbon Dioxide (CO2) concentrations in the parts per million range (PPM)and is ideal for applications ranging from conference rooms to home gyms. The CO2-2000 is easy to install and support. Measurement output is via a 4-20 mA current loop or a 0-10V interface. Low power consumption makes the CO2-2000 perfect for battery-operated or other power sensitive applications. A clear, bright LCD display option is readable from any angle for installations where local annunciation of the CO2 concentration is desired.
