Principle of operation:
The HC51M analyzer’s electrometer measures the current generated by the
ionization of the carbon atoms in the flame fueled by a hydrogen/air mixture.
To distinguish between total and non-methane hydrocarbons an optional
converter is used to oxidise all the non-methane hydrocarbons. The
temperature controlled pneumatics prevents condensation.
The flow is automatically adjusted and the instrument is provided with
automatic ignition of the flame in case of flame out or power failure.
The HC51M features a built-in zero/span solenoid valves to perform manual,
automatic and remote zero/span checks.
Real time calibration graphs can be displayed during span check operation.
Multi-tasking software, combined with the LCD graphic display, gives the
user easy and fast access to the instrument set-up, status and maintenance
parameters.
Real-time synoptic, auto-diagnostic and maintenance data screens can be
displayed while the instrument is operating. The automatic response time
function determines the measurement integration time best suited for the
measurement of hydrocarbons concentrations.
The built-in RS232 interface and digital communication protocol allow full
PC instrument emulation for remote control and troubleshooting as well as
a common serial link, thus achieving a fully digital air pollution monitoring
station.
