Brief introduction: Thermal conductivity type hydrogen analyzer is different according to the thermal conductivity of different gases and determine its composition. Through the measurement of thermal conductivity of mixed gas to some kind of gas content in the mixed gases, the highest thermal conductivity of hydrogen in the gas mixture, seven to eight times higher than nitrogen, oxygen and other, therefore, when the background gas in the mixed gases, or other ingredients keep constant thermal conductivity of mixed gas basic depends on the amount of hydrogen, such according to the mixed gas thermal conductivity is different, can be measured by how many containing hydrogen. Technical parameters: Measuring range: 0-100%, 0 1% and 0-10%, 35-75%, and 40-80%, 75 100%, 90-100%, etc. (other range can be set according to the user) Zero drift, plus or minus 2% FS / 7 d or less Span drift: plus or minus 2% FS / 7 d or less Linear error: plus or minus 2% FS Heavy after sex: 0.5% or less Response time: < 15 s Determination of value of output: 0/4-20 ma; RS485 / RS232 (optional) Ambient temperature: 5-45 ℃ Power supply: (220 + 22) VAC (50 + / - 0.5 Hz Power: 120 w Weight: approximately 8 kg Scope of application: Used for continuous automatic analysis of mixture gas, the content of hydrogen in high accuracy, simple structure, small amount of maintenance, long service life, etc. The analysis of the hydrogen content in the fertilizer plant synthetic ammonia process. Thermal power plant hydrogen cold hydrogen concentration monitoring in the system. Plant inside the containment of hydrogen leakage monitoring and hydrogen cold hydrogen concentration monitoring in the system. All kinds of combustion experiments of gas content in the laboratory. Steel blast furnace gas analysis. System QiZhan or other gases on the analysis of the hydrogen purity.
