Sample Ports: two samples’ analyzing ａnd two samples’ degassing concurrently

Control System: programmable solenoid valve system with high integration ａnd strong anti-interference ability, enhance instrument’s stability ａnd life

Pressure Measurement: imported sectional measuring dual pressure transducer, notably improve the measuring accuracy at low P/P_o point, 0-1000Torr, 0-1Torr ａnd 0-0.1Torr three transducers are equipped

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%）

Vacuum Pump: built-in bipolar vacuum pump controlled by patented software which can auto control pump’s start/stop

Dewar Vessel: imported 4 liter metal made Dewar can provide at least 72 hours of unattended measurement without refilling the Dewar

Partial Pressure: P/P_o controllable accuracy range is 5x10^-6-0.998

Ultimate Vacuum: bipolar pump: 4x10^-2Pa （3x10-4Torr）, molecular pump: 5x10^-6Pa
