The O2-A3 Alphasense Oxygen Sensor (formerly known as the AP-0004) is a plug-in replacement sensor for hand-held gas detectors that use an O2-A3 sensor. Gaining precise oxygen measurement is critical for industries that require its use for safety, medical, air quality or specialized process.
It is important to verify the sensor you are replacing has an AlphaSense O2-A3 printed on the side before ordering. Due to our low prices we cannot accept returns for the wrong sensor.
