Tips: Case Study - Portable Hydrogen (H2) Gas Detector for Fuel Cell Company

A new energy company has been engaged in research and development, testing and production of various fuel cells for many years. The company has many hydrogen pipelines for the hydrogen (H2) is the main power source in the production process. To prevent the substandard process from the leakage of the hydrogen, the engineer made an inquiry about detecting the leakage of hydrogen to us.

They needed a portable hydrogen detector to detect H2 leaks at the ports of each pipeline, record the detection value in real time and save a set of data every 2s recording interval. Furthermore, they also required transmitting the data to computer for the analysis.

After the communication with the engineers based on their requirements, we recommended them a portable hydrogen (H2) gas detector ATO-GAS-H2, with measuring range of 0-1000ppm and resolution of 1ppm and also with data transmission and storage function.

After using this H2 gas detector for a period of time, they were very satisfied with the detection results. The hydrogen gas detector not only is accurate in detection, fast in response time, but also real-time records the detecting value and save the data.
