    Handheld Carbon Monoxide (CO) Gas Detector Details

    Applications

    Portable carbon monoxide detector, pump suction style, is used to measure the CO concentration and give an alarms in the confined space like tunnel, sewer, undergroud shaft, mines, cement plant, thermal power plants, agriculture, refinery and other industries, to effectively prevent the carbon monoxide poisoning accidents.

    Carbon Monoxide CO Gas Detector Applications

    Tips: What are the differences between pump suction and diffusion type gas detector?

    A suction style gas detector is equipped with a small air pump. When it works, the pump draws the air sample from the tested region and sends the sample into the instrument for detection. The pump type gas detector features fast detection speed and remote measuring for dangerous areas, so as to maintain personnel safety. Other characteristics are the same with that of diffusion type gas detector.

    A diffusion type gas detector is used for detection to sample the air by the free flow of air in detection area. Such a measuring method is easily to be affected by the detected environment, such as ambient temperature and wind speed.

    Basic Settings of Portable Gas Detector

    This video will show you the basic settings of ATO portable gas detectors including high/low alarm setting, language setting and time setting.

    Calibration of Portable Gas Detector

    This video will show how to calibrate the ATO portable gas detectors.

    Concentration Detection of Pesticides Gas
    Methyl bromide is an organic compound with the chemical formula CH3Br, which is mainly used as a pesticide, fumigant, refrigerant and solvent, and can also be used in organic synthesis.This video will mainly use methyl bromide and CH3Br as examples to introduce the detection of their concentrations.

    How to Detect Hydrogen Sulfide Concentration in the Toilet
    Hydrogen sulfide is a flammable acidic gas that smells like rotten eggs at low concentrations and is very toxic. In actual operation, it is necessary to ensure that the detection equipment or method used can accurately measure the concentration of hydrogen sulfide, and pay attention to safety issues during operation to avoid hydrogen sulfide poisoning.

    How much C2H4 (ethylene) do ripe bananas and apples produce?
    We have various gas detectors such as: CO, O2, O3, H2, NH3, H2S, CH4, Cl2, CH2O, etc, from 0~10000ppm, Industrial or daily use.

    Existing reviews of Handheld Carbon Monoxide (CO) Gas Detector, 0 to 500/1000/2000 ppm
    Here are some questions
    I am very interested in your sensor mentioned above with options for detection levels even as low as 0-10 ppm with high resolution. I would appreciate if you can answer the following:
    1. What is the underlying technology (e.g. electrochemical, catalytic bead oxidizer)?
    2. Is presence of other gases a concern? (e.g. CO detection registering as H2)
    3. How often is calibration required?

    ATO Responded
    1. Principles of electrochemistry.
    2. CO and H2 are two gases that interfere with each other.
    Can you tell us what are the composition and concentration of each gas in the measured gas environment? Also, the pressure temperature and other ambient temperatures.
    3. Normally calibrate once a year.
    Reliable CO detector
    This carbon monoxide detector is reliable. Just place it in the right area, and the detector will quickly detect the carbon monoxide concentration. Works fine as described.

    High-quality and easy to operate
    We bought this portable detector to ensure the safety of our laboratory experiments with a mixture of gas containing H2 and CO (we also have this company's H2 detector). The CO detector becomes useful for examining the connections for potential leakage. So far, I can say that it is fairly straightforward to handle and operate. Also, shipping to Canada was fast.

    I need a pump-type detector to detect H2S and CO2 gas.
    Hello. I need a pump-type detector to detect H2S and CO2 gas. Can H2S and CO2 detector come in one unit? What is the shortest sampling time? What is the memory size (how many data points it can record before getting full)?
    From: Brandon | Date: 23/07/2020
    Was this review helpful? Yes No (0/0)
    ATO Responded
    Hi, Brandon. As required, the gas detector of H2S (0-500 ppm) and CO2 (up to 5%) can be provided in one unit. It is pump-type detector, and the shortest sampling time is less than 10 seconds. It can record ten thousand data points.
