Tips: The necessity of a hydrogen gas detector

Hydrogen (H₂) has the physical properties of colorless and odorless, and the flame is transparent when burned. Therefore, the presence of hydrogen in the environment is not easy to detect by the senses. Generally, Ethyl mercaptan is added to the hydrogen gas so that it can be detected by the senses and make the flame appear color. However, when judging whether hydrogen has leaked, we cannot judge by ignition. Because using an open flame to check hydrogen is tantamount to igniting a time bomb, which is very dangerous. Therefore, it is necessary to use a hydrogen gas detector to monitor the environment where H₂ may leak on-line.

Hydrogen is mainly stored in liquid form. The liquid H₂ overflows and evaporates suddenly in a large area, which can also cause hypoxia in the environment, and may form an explosive mixture with the air, causing a combustion and explosion accident.

ATO hydrogen gas detector is an instrument that can continuously detect the concentration of H₂ in the environment. It uses the natural diffusion method to detect the H₂ concentration, with an electrochemical sensor. The use of hydrogen detectors can reduce the occurrence of H₂ explosion accidents.

How to Calibrate a Fixed Gas Detector?

This video introduces the zero calibration process of a fixed gas detector. When the air is clean, press the menu first, then press the "+" key to enter F04, then press the OK key, and then press the BACK key. The detected data will become zero. Prepare the standard gas, we use isobutane for calibration.

Step 1: Press the menu, then press the "+" key to enter F07, change the data to the same as the standard gas value, and press OK.
Step 2: Press the menu, then press the "+" key to enter F08, now you will see it shows 0, change it to 1, and then press the OK key to return.
Step 3: Connect the sensor to the standard gas, the gas flow rate is 500mL/min, and press the OK key after the data stabilizes.

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.

About fixed gas detector

Can the fixed detector directly detect H2 in combustion exhaust containing CO2, N2, O2 and some other minor components (the temperature is not high)? The H2 flow rate varies.
