Thermal Conductivity Analyser – 2020
Model 2020 Thermal Conductivity Analyser 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.
- 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 analogue 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
