    CO-A4/CO-A4+ Carbon Monoxide Sensor

    CO-A4/CO-A4+ Carbon Monoxide Sensor

    The CO-A4 sensor is a PPB sensor that is designed for industrial safety and environmental air quality applications with best-in-class baseline stability. The A series is the most widely used sensor format for portable gas detection applications. This product is available in our standard format (CO-A4) and with our patented Integrated Smart Technology (CO-A4+) that has an IST board with a memory chip and temperature sensor integrated in the sensor. The + sensors store specific calibration, specification, and identification

    data on every sensor allowing plug and play operation. The on-board temperature sensor improves the accuracy and simplicity of temperature compensation algorithms.
