GasLab AlphaSense O2-A2 Oxygen Sensor AP-0001

The AlphaSense O2-A2 oxygen sensor is a replacement sensor for hand-held gas detectors that use an O2-A2 sensor. Features Electrochemical (EC) sensor designed to last for up to 2 years Good pressure and temperature independence Small, compact & maintenance free The EC board or development kit converts the sensor’s analog output current to a voltage that is measured by a high-resolution analog to digital converter. The digital voltage is corrected and compensated for temperature and pressure by a microcontroller to produce an accurate gas concentration measured in ppm (parts per million). This can be read as serial UART output or can be logged in internal memory for later retrieval. In addition the board makes it easy to apply zero or span calibration. Models AP-0001 O2-A2 Sensor – Plug-in replacement sensor for many oxygen safety monitors or for integration into OEM oxygen safety products. CM-32911 O2-A2 Sensor Development Kit – Easy to use, simply plug the EC 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 O2-A2 Sensor EC Board – Same functionality as the development kit without USB cable or software.
