Product Features: 

 Thermal conductivity of hydrogen, argon, helium analyzer can be used for continuous automatic analysis of a variety of gas mixtures of hydrogen percent concentration. With high accuracy, simple structure, small amount of maintenance, long service life. 

 Basic principle: 

 The instrument is the use of various gases of different thermal conductivity, ie, have different thermal conduction velocity measurements. When the measured gas at a constant flow rate of inflow of analytical instruments, thermal conductivity pool platinum thermal resistance wire resistance due to the measured gas concentration changes, the use of a Wheatstone bridge the resistance signal into electrical signals. circuit processing, signal amplification, temperature compensation, linearization, making the measured values.
