. 
Second, the use and scope of application: 
The JNYQ-H- 31 digital hydrogen analysis instrument can be used to continuously and automatically analyze the percentage concentration of hydrogen in various mixed gases. 
The structure is suitable for installation in complete sets of equipment, and has the characteristics of simple structure, small amount of maintenance, long service life and so on. 
It is suitable for non-explosion-proof places such as thermal power plants and chemical fertilizer plants, and can also be used in scientific research institutions and laboratories. 
. 
3. Typical application areas: 
1. Power plant: purity analysis of hydrogen for cooling in generator hydrogen cooling system and measurement of hydrogen content in the environment. 
2. Chemical fertilizer plant: hydrogen content in fresh gas and circulating gas in nitrogen fertilizer synthetic ammonia process. 
3. Iron and steel plant: analysis of clean gas after dust removal of blast furnace gas. 
. 
Fourth, the working principle: 
The working principle of JNYQ-H- 31 digital hydrogen analysis instrument is to determine its composition according to the thermal conductivity of the gas, that is, the content of hydrogen in the mixed gas is determined by measuring the thermal conductivity of the mixed gas. this series of thermal conductivity detectors have the characteristics of high precision and strong stability.
