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.
