The O2-A2 Alphasense Oxygen Sensor is designed to monitor 25% oxygen levels by volume. The sensor is most sought after as a replacement sensor for handheld gas detectors that use the O2-A2 sensor.
Features
- Electrochemical Sensor measures up to 25% Oxygen
- Barometric Pressure, Temperature and % Relative Humidity Sensors
- Smart EC board Adds RS485 with Optional
- Easy Integration; Compact & Low Power
Models
- O2-A2 Sensor Only – Sensor only. Designed for integration into high-volume OEM products or as a replacement oxygen sensor in these 4 gas analyzers:
- CM-32911 Development Kit – Easy to use, simply plug the board into your PC via the included serial UART to USB cable. Use our free GasLab® software to measure and graph oxygen levels, barometric pressure, temperature, and % relative humidity. Includes on-board memory for data logging.
- CM-32910 Smart EC Board – Same functionality as the development kit without USB cable or software.

Accessories
easily convert 20mm standard gas sensors from diffusion to sampling sensors. Molded polymer. Tube cap adapters are not pre-installed. For accurate results you must .
. Custom USB cable enables RS485 communication to GasLab Software for EC Sensor Board and Development Kit.
includes all the tools you need to utilize the tube-cap adapters as part of a sampling sensor system.
is a highly selective, semi-permeable membrane to water vapor. If gases inside Nafion tubing are wetter than gases surrounding the tubing, drying will occur. If the surrounding gases are wetter, humidification will occur.
provide a constant flow of air across the sensor with a tube cap - perfect for bench-top testing of sensors for closed-loop sampling applications.
gives a strong and secure container to mount the sensor. Hydrophobic filters available for enclosure for outdoor use.
