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
0.1% of real reading, better than 0.1% 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 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.
