The MO-200 is designed to measure 0 to 100 % oxygen and is connected to a hand-held meter via cable that displays and stores measurements. The wide measurement range allows it to be used for applications either in the soil or in the lab with the diffusion or flow-through head accessories. The sensor is housed in a polypropylene body and electronics are fully potted. Typical applications include measurement of O2 in laboratory experiments, monitoring gaseous O2, in indoor environments for climate control, monitoring of O2 levels in compost piles and mine tailings, monitoring redox potential in soils, and determination of respiration rates through measurement of O2 consumption in sealed chambers, or measurement of O2 gradient in soil/porous media.
The meter has a sample and log mode, and will record an average daily value. Sample mode will record up to 99 manual measurements. Log mode will power the meter on/off to make a measurement every 30 seconds. Every 30 minutes the meter will average the sixty 30 second measurements and record the averaged value to memory. The meter can store up to 99 averages, once full it will start to overwrite the oldest measurement with new ones. An average daily value will be recorded from the 48 averaged measurements (making a 24 hr period). Sample and log measurements can be reviewed on the LCD display or by downloading the data to a computer, however, the average daily value can only be viewed by downloading the data to a computer. Downloading data to a computer requires the AC-100 communication cable (a standard USB cable will not work) and ApogeeAMS software.
