Applications

Portable Nitrogen gas detector is used for the N₂ concentration detection in the electronic component storage, Nitrogen tank area, food packaging, Nitrogen cylinder and tank purity measurement, laboratory, etc.

Tips: Why you need a Nitrogen (N₂) gas detector?

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.

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.

Portable Oxygen Gas Detector with PC Interface

The Smart Handheld Gas Detector from ATO is designed to detect oxygen in a range from 0% to 30%. In this video, ATO will show you that the detector uses a micro sampling pump to draw in the measured gas with the max flow rate up to 1L/min. The LED display provides simultaneous pickup of gas variety, density units, the maximum value, local time and atmospheric temperature, etc.

Existing reviews of Portable Nitrogen (N2) Gas Detector, 0 to 100% Vol

Please advice

We purchased the handy N2 gas detector and trying to set it up to use for our application. We generally pressurized the pipe the 99.9% pure N2 and want to make sure all connections are tight and leak-free.
The model mentioned in the subject starts after power is on -
The pump starts and the display shows an N2 volume 100% low 79 and high 83.
After that it just shows 100% N2 in the air and continuously beeping. I think it's detecting the N2 in air. How can I calibrate the instrument so it will not detect the N2 in the air and only beep when the tip is close to the leak point? I check the online manual but it's not very helpful.
