Thermal Conductivity Analyzer

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
• ndependent 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
