    Carbon Dioxide Gas Detector Applications

    Carbon Dioxide CO2 Gas Detector Applications

    1. Carbon dioxide detector in animal husbandry
    The quality of air is related to the healthy growth of animals. If the air is turbid for a long time, the concentration of carbon dioxide is high, and no ventilation is available, it will lead to animal disease or epidemic outbreaks. Therefore, a carbon dioxide detector is really necessary to keep measuring the concentration of CO2, so as to prevent the occurrence of animal epidemics.

    2. CO2 gas detector in industry
    Carbon dioxide (CO2) detector is widely used in industry, such as waste water treatment, safe production, and especially in underground operation where it is very necessary to monitor the concentration of carbon dioxide. Carbon dioxide detectors are also widely applied in metal processing, pulp and paper making, cleaning and solvent extraction, cryogenic cleaning and other CO2-related industries.

    3. Carbon dioxide detector in public places
    In crowded places, such as conference rooms, classrooms, exhibition halls, hospitals, shopping malls, bars, restaurants, airports, railway stations, entertainment halls, etc., carbon dioxide detectors can be installed for ventilation control and environmental quality monitoring, so as to protect people's health.

    4. CO2 gas detector in agriculture
    Carbon dioxide is related to plant photosynthesis, so the CO2 detector is widely used to monitor whether the concentration of carbon dioxide is enough. Appropriate concentration of gas fertilizer can increase the yield of agricultural crops. When carbon dioxide concentration is insufficient, gas fertilizer can be used, which is very helpful for crop growth and gain in crop yield.

    Existing reviews of Portable Carbon Dioxide (CO2) Infrared Gas Detector, 0 to 2000/5000/10000 ppm
    Carbon dioxide gas detector with data logging
    For your carbon dioxide gas detector, has it the option to record measured values like a Data Logger and then transmit the recorded values to user's PC?
    From: Butler | Date: 11/07/2019
    Was this review helpful? Yes No (1/0)
    ATO Responded
    Yes, the CO2 gas detector has the optional function to record the measured values and transmit the data to PC by USB for downloading and printing.
    The gas detector I am looking for
    So I am looking for a sensor that can sense nitrogen gas concentration in the system at an acceptable level. The N2 is being flooded into the system to help suppress oxygen and create a less combustible zone (it has been confirmed by a P. Eng that it is NOT an explosion rated situation). Other possible gasses include standard air and minute traces of ethanol (to the point that they may as well not be there). Gasses in the area are constantly evacuated by a fume scoop.

    ATO Responded
    As per your described gas environment, our N2 Gas Detector: ATO-GAS-N2, 0 to 100% Vol will work effectively.
    Can your portable gas detector work under (7-8 bar) pressure?
    Can your portable gas detector work under (7-8 bar) pressure?
    From: Janathan | Date: 12/12/2021
    Was this review helpful? Yes No (0/0)
    ATO Responded
    No, it can not work properly, because the pressure is too high (7-8 bar), it can work only under pressure of 1 bar.
    Already used, great detector
    During a power outage, the power supply in my house burned out, and I had to use a gas fireplace. The area that can be detected is very large. When carbon dioxide is detected, the device will beep and beep. Use this detector to let I am at ease.
