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 principles 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. Kind of Gas Relative thermal conductivity (at 0°C)expressed taking that of air(5.572 × 10-5cal/cm.sec. deg.)as 1 Sulfurdioxide SO2 Carbondioxide CO2 Argon Ar Carbon monoxide CO Water vapor(100°C)H2O Air Nitrogen N2 Oxygen O2 Methane CH4 Hydrogen H2 Measuring mode: 1 range or 2 ranges (for measuring the same sample gas components with the same FEATURES measuring system) Measuring range: CO2 1. Continuous measurement possible. 2. Quick response. 3. Integral unit incorporating detector, current regulator and indicator. 4. Simple and robust mechanism assuring high maintainability. 5. Minimum influence due to external and operating conditions. 6. Stable accuracy. H2 0 to 10 ....100 100 to 90 .... 0 0 to 3 ....100 100 to 95 ....
