Alphasense Carbon Monoxide CO-AF Sensor
Price in Sri Lanka

The AlphaSense CO-AF Carbon Monoxide Sensor provides an accurate and reliable way to measure up to 5,000 ppm CO by volume. The smart board and development kit convert 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 logged in internal memory for later retrieval. In addition, the board makes it easy to apply zero or span calibration.
