Alphasense O2-A3 Electrochemical Oxygen Sensor – 25% Range, Smart Output, 3-Year Operational Life

Description

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.

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.
