THERMAL CONDUCTIVITY GAS ANALYZER THERMOMAT
DATA SHEET
ZAF
In modern industries, it is indispensable to analyze
components and measure concentrations of mixture gases
and combustion gases for strict quality control and to file data
for establishing production schedules which will allow proper
management of industrial processes.
Of the various analytical methods and measuring prin-
ciples available for analyzing process gases, this gas analyzer
utilizes the fact that electric resistance of a heated platinum
wire changes depending on kind and concentration of gas.
