    Tips: Why a Nitrogen (N2) gas detector is necessary?

    Nitrogen (N2) is usually a colorless, odorless gas and generally it is less dense than air. Nitrogen is one of the main components of air, accounting for 78.08% (volume fraction). Under the standard atmospheric pressure, when nitrogen gas is cooled to 195.8℃, it turns into a colorless liquid; when cooled to 209.8℃, the liquid nitrogen becomes a snowy solid. Nitrogen is often used as a preservative because it is chemically inert and difficult to react with other substances at room temperature.

    Nitrogen seems to be harmless, but it is still dangerous. If the concentration of nitrogen in the air is too high, the pressure of oxygen in the inhaled air will drop, thus causing hypoxia and asphyxia. When the concentration of inhaled nitrogen is not too high, the patient initially feels chest tightness, shortness of breath and weakness; then there are others symptoms: irritability, extreme excitement, running, screaming, absent-minded, and gait abnormality, known as "nitrogen tincture", entering a drowsiness or coma. When the inhaled nitrogen is at a high concentration, the patients can quickly become unconscious and die from respiratory and cardiac arrest.

    It is really necessary to detect the nitrogen concentration before personnel enter tanks, confined spaces, or other areas of high concentration. ATO portable nitrogen gas detector adopts the pumping sampling method, which can quickly and accurately detect the concentration of nitrogen and give the alarm. Thus, the personnel can also check the data in the N2 gas detector and make sure the nitrogen concentration in the confined space meets the standard before the operation, so as to ensure the safety of personnel.

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

    The N2 gas detector arrived on time with good packaging.
    The N2 gas detector arrived on time with good packaging. Use it to detect the gas leakage in the Nitrogen tank area. Light, portable and easy to use. Works as advertised. The detector is great helpful to find the danger and gives us sound and vibrating alarm.

    Portable gas detector working pressure
    Can your portable gas detector work under (7-8 bar) pressure?

    ATO Responded
    No, it can not work properly because the pressure is too high (7-8 bar). Our portable gas detectors can work only under pressure of 1 bar.
