Thank you for purchasing the Smart Wireless Oxygen in Air Sensor. We pride ourselves on producing high quality products that meet with the demands of the busy classroom environment. If you have any problems using this sensor, please read this documentation in full before contacting the Data Harvest support team. 


The smart wireless oxygen sensor is a 4 channel sensor measuring oxygen (%), temperature (oC), pressure (kPa) and humidity (%RH). 

It can be used to study respiration, breathing, photosynthesis and the rate of oxygen evolution some chemical reactions. The sensor is an electrochemical device that has a life span of approximately 5 years. Calibration is available to compensate for deterioration of the sensor output or set the oxygen level to local conditions.
