O2-A1 Alphasense 25% 1 Year Oxygen Smart EC Sensor
The O2-A1 Alphasense Oxygen sensor is designed to provide engineers, scientists and students an accurate and reliable way to measure up to 25% oxygen levels by volume. This sensor is a low cost, industrial safe, oxygen module designed to last one year.
Features
- Electrochemical Sensor measures up to 25% Oxygen
- Smart EC board adds Barometric Pressure, Temperature and % Relative Humidity Sensors
- Smart EC Board Adds Serial UART Output
- Smart EC board Adds RS485 with Optional RS485 Cable
- Easy Integration; Compact & Low Power
Models
- O2-A1 Sensor Only – Sensor only. Unlike partial pressure oxygen sensors, they have good pressure and temperature dependence, making them the best choice in safety applications.

Free Easy-to-use GasLab® Software
The Smart EC board uses GasLab® software for setup, calibration, data logging, and real-time data analysis. GasLab® makes it easy to export data into a .CSV file that can be imported into any industry-standard software or spreadsheet. GasLab® runs on Windows XP or higher, and free to use with our products.
System Requirements
- Windows XP SP2 or newer
- Microsoft .Net 3.5 Runtime Libraries
Accessories
- Tube Cap Adapters 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 mount the tube cap permanently.
- RS485 Cable. Custom USB cable enables RS485 communication to GasLab Software for EC Sensor Board and Development Kit.
- Micro-Pump Kit includes all the tools you need to utilize the tube-cap adapters as part of a sampling sensor system.
- Nafion Tubing 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.
-
Micro Gas Sampling Pumps 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.
