It only stays on for about 2 minutes. Im doing Covid testing in a parking garage , no ventilation. Testing done in their cars. I need to know what the levels are.

    Very dependable CO sensor for it's price range
    For most part, Smart Sensor ST9700 performed well as intended. Instructions were useful and the devise was very simple to operate. After the initial set up, it took a little time to start getting readings of Carbon Monoxide. It should be emphasized that due to lighter density of Gas vs Air, the sensor would give higher readings indoor at 5 feet or more above floor.

    Very handy device.
    Very handy little device which reads carbon monoxide concentration down to less than 5 ppm. Some people will experience problems starting at about 11 ppm even though various standards allow 8 hrs. at 20, 50, or even 70 ppm. It explained to me why I get headaches when

    Best priced item
    Good for detecting dangerous levels of CO, not so good for detecting trace amounts for scientific measurements.
