                  RD-400 thermal conductivity of hydrogen analyzer
                  Published:2013-8-24   Views:4279
                  RD-400 conductivity hydrogen analyzer
                  One, overview
                  The RD - 400 type conductivity hydrogen analyzer is based on the working principle of thermal conductivity of different gas, the thermal conductivity gas sensor and signal transducer consisting of a new generation of intelligent online analytical instrument.
                  Two, the main use of
                  The instrument is widely used in chemical fertilizer, chemical, metallurgy, heat treatment, generator cooling, air separation, analysis of hydrogen concentration on-line hydrogen in industrial production.
                  Three, characteristics
                  • sensor platinum sensitive element coated with glass film, not with the measured gas direct contact and sensor has stable performance, high sensitivity, good corrosion resistance.
                  • microcomputer, large screen LCD
                  • the man-machine dialogue, Chinese menu function selection
                  • paperless recorder with the function, test data, automatic storage
                  • measurement alarm set
                  • communication port RS232
                  Four, the main technical parameters
