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.
Note: Once an electrochemical (EC) sensor is purchased from CO2Meter.com and the sealed packaging is opened or the sensor module is installed, it is no longer eligible for return due to the limited operational lifespan that begins upon activation.
**Please Note: Minimum Order Quantity 10pcs – 6-8 week lead time**
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.
