Smart EC Sensor for up to 25% Oxygen by Volume

The Alphasense oxygen sensor has been designed to provide scientists, engineers and students with a reliable and accurate way for measuring up to 25% oxygen levels by volume.

The circuit board's microprocessor offers zero and span calibration as well as temperature, barometric pressure and % relative humidity sensors. When used in a remote device, the sensor features on-board memory to log data.


  • Circuit board adds RS485 industry-standard interface
  • Effortless integration; low power and compact
  • Electrochemical (EC) sensor measures up to 25% oxygen
  • Circuit board includes barometric pressure, temperature and % relative humidity sensors
