[Signal Instruments] Heated Total Hydrocarbon Analyzer
Signal instrument, Heated total hydrocarbon analyzer
Specifications
The hydrocarbon analyzer has a totally automatic microprocessor-based operation including: auto-ignition, auto-calibration, auto-range with ID and auto-purge on shutdown. This makes the instrument ideal as a "smart" stand-alone unit or as a "building block" for systems integration via a RS-232 communications port. Automatic diagnostics and fully-configurable alarms are also integral to the hydrocarbon analyzer.
A large multifunction, backlit LCD provides a clear display of hydrocarbon concentration measurement, range, sample flowrate and the status of critical operating parameters (oven, catalyst and flame temperatures, fuel, air and sample pressures, DC and bias power supplies). The intuitive, menu-driven interface and soft key buttons enable the operator to quickly configure and control the monitor's function. The unit features 19" rack mounting at 3 RU height and a weight of only 35 Lb. It has a dual voltage capability of 115 VAC and 230 VAC, selectable from the rear panel. CE marked.
