Hydrocarbon Analyzer Monitors for Ambient Air Contaminants.
The McFID, which is based on the highly sensitive Flame Ionization Detection methodology, provides continuous on-line measurement of up to 4 different speciated hydrocarbons using a microprocessor controlled chromatographic separation technique. This analyzer can conduct exposure monitoring of hydrocarbon-based airborne contaminants regulated by OSHA standards.
The McFID can monitor single or multiple locations with the addition of appropriate sample stream switching. Instrument sensitivity ranges from 0 to 1 ppm full scale, up to percent by volume concentrations. The McFID's advanced measurement bench is separated into two discrete parts. The electronics section is separated from the pneumatics/detector section by a set of partitions. Coupled with the explosion-proof burner assembly, the McFID meets international safety standards without using a continuous dilution purge, a first in an instrument rated for General Purpose environments.
The McFID is available as a stand alone 19-inch rack mounted analyzer or as a "module" that can be linked into a multi-measurement analyzer system integrated by a high speed digital data network. Standard NGA Series features include: embedded temperature, pressure, and flow sensors with continuous monitoring of these variables; autoranging and remote ranging capability; four standard full scale ranges; and advanced "component level" diagnostics. Optional features include: alarms; autocalibration; current, voltage or serial outputs; and a selection of RS232 and RS485 AK or Modbus protocols.
