V-Sorb 2800S specific surface area
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 controller electromagnetically
operated 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 0.15% of real reading, better than 0.15% of F.S. (full-scale).
2. 0-10Torr (optional) and 0-1000Torr dual pressure 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 assembling-installed 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.
