Setavap3 Automatic Vapour Pressure Analyser

Part Number 80500-0

Setavap3 provides reliable, precise and fully automated vapour pressure analysis.

Integrated shaker
Simple operation
Minimal bias
Robust and compact design

With a colour touch screen, the Setavap3 provides a clear user interface to guide the operator through the menu system and simple operator sequence.

For precise results, the minimum dead volume design eliminates sample carryover, it is suitable for high ethanol content fuels. A fully automated test sequence removes possible operator bias.

Results are stored in a 16GB internal memory which can be viewed on the screen. For data management and analysis, results can be saved directly to a USB memory stick, LIMS compatibility and printing is provided via Ethernet or Serial Ports.


ADDITIONAL INFORMATION

Measurement Principal
A motorised piston with an internal pressure transducer draws sample into a temperature controlled measurement chamber. The chamber is automatically sealed and the piston expands the headspace to create a vacuum to the required vapour/liquid ratio. At the same time the chamber is heated to the test temperature. Vapour pressure is recorded. There is no requirement for an external vacuum pump.

Triple and Single Expansion Methods
Setavap3 is compliant with both types of test and will report both DVPE or VPx.

Innovative Design
The measurement chamber and valves are temperature controlled using electronic peltier cells for heating and cooling. A unique surface finish and coating to the bore of the chamber extends durability and sealing integrity. A high precision linear actuator with digital encoder feedback is used for exact piston positioning.

Calibration & Verification
Calibration of the Setavap3 can be performed in the field, eliminating the costs and time associated with sending the instrument to a service centre.

Service & Maintenance
The rugged design ensures minimal operational maintenance is needed. An automatic gravity feed lubricating system supplies lubricant to the piston and valves, to ensure that all moving parts and seals provide a long service life.
