Software Features
The FINESORB****0 is controlled by powerful Windows R–based
operating software. It provides all the convenient features you
are accustomed to when using Windows-based programs.
Point-and-click operations, pull-down menus, access to multiple
printers and network drives, multitasking capability, and much
more featured in the FINESORB****0 user interface.
Additionally, familiar Windows format reduces the time required
for training new operators, which improve the efficiency more.
The principle diagram of each process visually displays on the
screen, so the status of each valve can be intuitively known.
The process of dynamic test shows the state of each valve.
Show the value of each detector and sensor and display digital
quantity or curve according to the needs.
Display the setting parameter value in programming time,
convenient to compare with the measured value.
Visually display the state of each device, normal operation or
alarm state.
The carrier gas and reaction gas in the process of test, and
whether to use steam generator can all be controlled by
software program.
Purging time in test process can be controlled by program.
The temperature of the stove can be heated in maximum *0
sections of program and can automatically save programming
state. The control module has the function of automatic
correction and learning with precision 0.*2℃.
The temperature of TCD thermal conductivity cell can be
programmed control, according to the need to set thermostatic
temperature, and can always maintain high precision constant
temperature with precision 0.*2℃.
The constant-current source by numerical control can be
programmed output, and can keep high precision constant-current
with precision 0.1%.
The temperature of steam generator also can be programmed
control, choose appropriate temperature according to the
evaporation temperature of liquid.
The temperature of condensation-preventing system in pipeline
and gas path also can be programmed control, make the equipment
be in normal use in bad environmental conditions.
lIn the process of test, the software can record
and display some important parameters. Sampling data will
automatically treat after the test.
It is able to process the
measured data into report and mark manually
The data can be imported to EXCEL or ORIGIN.
