Looking for H2 and H2S Detector for Experimental Vacuum Apparatus

Hello, we are a company whose main field of activity is vacuum technology. We're building an experimental vacuum apparatus for the academic sector and need to monitor H2 and H2S gases with safety sensor(s) (On/Off). Based on the sensor signal, the technology will be stopped and an alarm will be raised. Can anyone offer a solution from their portfolio or recommend something?

In your experimental vacuum apparatus, what is the concentration of H2 and H2S gas? And what are the temperature and pressure in the environment? Also, do you want to detect gas continuously for a long time? If so,

I've worked on a similar project before. It's crucial to get the concentration levels right. If you're working with low ppm levels, make sure the sensors can detect those ranges. Continuous monitoring systems with data logging can also help in analyzing gas leak patterns over time.

Thanks. The apparatus will be in an open frame inside the flow box. The H2 and H2S need to be watched out of the vacuum system. The system will be connected with pressure bottles (they will be outside the flow box) where there will be pressure of 2 - 3 bar. The max flow of one gas is assumed to be 30 sccm. There are perhaps all the details that I know at this time. Is it enough for you?

So, if you want to keep an eye on H2 and H2S leaking into the air from the vacuum system, we recommend our fixed gas detector. You can choose H2: 0-1000 ppm, and H2S: 0-100 ppm.
