Easy Calibration & Test Data Storage
An auto-zero feature for the gas sensors takes
even more of the work out of your hands. Span settings
are carried out by means of front-panel control switches,
and keypad controls remain functional during setup,
allowing the operator to select any analysis parameters
or fuels as necessary. All settings remain in memory –
even when power is turned off – and will be stored until
amended by the user or the analyzer is deliberately "cold
started" to clear the memory.
The 9950 stores up to 99 individual tests (including
a complete set of measurements and boiler ID number)
which are maintained in a non-volatile memory and can
be retrieved for printout for downloading via the RS-232
serial port.
Sample Integrity is Never in Question
Model 9950 accomplishes sample conditioning
through a fully integrated handling system capable of
delivering stack gas to the analyzer without
compromising integrity. A stainless steel probe is
connected to the monitor by a flexible hose. A high-
efficiency vane pump draws the sample through the
probe and into a coalescing filter where particulates and
condensates are removed prior to analysis, assuring you
the highest accuracy possible. Water and particulate
matter are automatically pumped from the system.
