notably improve the measuring accuracy at low P/Po point, 0-1000Torr
(0-133Kpa), 0-10Torr (0-1.33Kpa)
Transducer Accuracy: imported silicon thin film pressure transducer, accuracy
can reach 0.1% of real reading, better than 0.1% of F.S.(full-scale), far
accurate than Pirani resistance vacuum gauge(general error is 10%-15%)
Partial Pressure: P/Po controllable accuracy range is 5x10-6－0.995
Sample Types: powders, particle, fiber, flakes and other species
Adsorbate Gas: high purity nitrogen (≥99.999%), Ar, Kr, CO, CO2, C4H10
etc. non-corrosive gases are optional
Data Acquisition: high-precision and high integration data acquisition
modules, minimal error, strong anti-interference ability
Data Reduction: Windows®-based independent developed Gold APP softwareTM,
perfect versatility, produced full featured and multi-model reports
V-Sorb 4800 surface area and porosimetry analyzer features
A: Vacuum System
1. Unique integral manifolds system, decrease connecting
points apparently, reduce leak rate, improve ultimate vacuum.
2. Modularity design can configure as customer requests,
benefits future functions extension and instrument maintenance.
3. Germany imported bipolar vacuum pump, low noise, stable
working, oil-return prevention; ultimate vacuum can reach 4x10-2Pa
(3x10-4Torr).
B: Control System
1. Industry used programmable solenoid valve system,
strong anti-interference ability, convenient for installation and uninstallation.
2. Separated analysis and treatment manifolds can prevent foreign
matter to contaminate manifolds in sample treatment.
C. Measures for Improving
Accuracy
1. Imported silicon thin film capacitive pressure transducer,
accuracy can reach 0.1% of real reading, better than 0.1% of F.S. (full-scale).
2. 0-10Torr (optional) and 0-1000Torr dual transducers,
sectional measurement in pressure range can reduce errors in low vacuum,
0-10Torr silicon thin film transducer is highly accurate than Pirani resistance
vacuum gauge (general error is 10%-15%).
3. Unique monolithic manifolds system, decrease connecting
points and reduce leak rate apparently.
4. Original stepping coolant level control system, ensure
the coolant level unchanged when compares with sample cells in the whole
analysis process, completely eliminate the analysis errors caused by dead
volume change.
5. Pioneered gas outlet and inlet control system can
efficiently prevent sample splash in evacuation and gas inlet process,
guarantee clean manifolds and sample weight unchanged, avoid zero and liner
drifting caused by transducer’s macro-change.
D. Data Acquisition and
Reduction
1. High precision and integration data acquisition module
is easy to connect, minimal errors and strong anti-interference ability; standard
485 communication mode is good for analyzer’s applications extension and
interconnection, can also conveniently switched to RS232 and USB modes.
2. Multi calculating methods for data reduction provides
all-round sample analysis options; powerful data archiving and searching system
helps a lot for data management.
