The the Boxed Gascard transducer is a self contained IR CO2 sensor available in a variety of detection ranges. The transducer provided fast and reliable CO2 concentration data over a wide range of barometric pressures and environmental temperatures. It brings the accuracy and reliability of the Gascard non dispersive infra red technology to the convenience of a turnkey instrument. The Boxed Gascard® is suitable for CO2 monitoring in a diverse range of applications from anaerobic digestion monitoring to plant physiology, where the carbon dioxide concentration in air-like atmospheres needs to be measured from ppm to tens of percent concentration. The bit-switch controlled 4-20mA or 0-20mA output is ideally suited for interfacing with most data loggers. Alternatively, the optional RS232 interface and NG Logger software may be used to log the concentration information onto a PC (with a serial to USB converter) or suitable tablet computer. The aluminium enclosure provides a convenient packaging of the sensor and associated electronics ready to mount as a subsystem in other instrumentation. The unit includes a gas inlet port and filter but not a pump. If gas cannot be flowed through the system (this is not a diffusion sensor) with some positive pressure from the source then an optional external pump would be required.
