Wireless oxygen in air sensor-(ELS-LOG1300)

Data Harvest wireless oxygen in air sensor - This can be used to measure how the amount of O2 varies in the classroom and the variation of the rate of production in photosynthesis and respiration of small organisms such as microbes and maggots. Particularly useful with the wireless CO2 sensor, the gaseous exchange of a burning candle in a bell-jar can be measured and with no wires to attach, it is much easier. With the built-in pressure, relative humidity and temperature sensors, environmental measurements in Biology can take on a whole new meaning. A Nalgene bottle, into which it fits, is included to create a contained environment for study of plants and small animals. (NB. for gaseous use only - not for use in water). -
