The operator can program the system to measure each channel for a desired period of time before the multiplexer switches to the next sample. Just before switching, the CO₂  and H₂O concentrations are measured by infra red gas analyser and laser trimmed humidity sensors, along with the flow rate and the output of any other sensors connected to the 7 analogue inputs.

All of the resulting measurements are stored on the plug-in, SD memory card. When the experiment is concluded the SD card can be removed and plugged in to a card reader or SD card slot on a laptop PC. A high speed USB port is included for data transfer directly from the system.
