Thermal Conductivity Analyzer - 2020 Model 2020 Thermal Conductivity Analyzer is a versatile, explosion-proof, microprocessor-based instrument for measuring binary mixtures of gases. Model 2020 responds to the differences in thermal conductivity between various gases by continuously comparing the sample gas with a reference gas of known thermal conductivity. Features • Customer selectable gas constituents; 11 gases, 110 combinations • 6 gas concentration alarm set points • Automatic linearization • Auto Ranging automatically selects the proper preset range for a given measurement. Manual override allows the user to lock onto a specific range of interest. • A 2-line alphanumeric display screen (VFD), driven by microprocessor electronics that continuously prompt and inform the operator • Proven sensor cell design • Auto and remote zero cal capabilities • Independent zero and span correction • Two programmable alarm relays and a system failure alarm • Two way RS-232 serial digital port for use with a computer or other digital communication device • Four analog outputs: two for measurement (0-1VDC and isolated 4-20mADC) and two for range identification • Extensive self-diagnostic testing at start-up and on demand with continuous power supply monitoring
