The H-1640B.4F PAV3 features a compact, benchtop design with integral ASME code section VIII, division 1; 1992 A 93 pressure vessel controlled using a 7″, full-color, touch-screen display, which is tilted for greater visibility. Operating pressure is 2.10 ?0.05 MPa (304psi). Temperature is 80 to 115°C (176 to 239°F) and programmable from 50 to 150°C (122 to 302°F). Between 80 to 115°C (176 to 239°F) the tolerance is well within ±0.1°C. Temperature uniformity is ±0.5°C. Pressurization is programmable from 1 hour to 99 hours. This enables AASHTO R28, ASTM D5621, and EN 14769 specifications to be met without any special programming and also enables greater freedom for research and development projects. Real-time graphs are visible from the touch-screen controller while the unit’s network-ready modem enables the PAV3 to be controlled from PCs and mobile devices when connected to a network.
Data acquisition of temperature, pressure, and time is collected throughout the aging process. Once the aging process is complete, a .csv file can be created and saved via the USB port on the front of the PAV3. Once the .csv file has been created, it can easily be viewed and manipulated in Microsoft Excel or other spreadsheet programs.
The PAV3 sample holder is a one-piece, solid device requiring no assembly and is easy to achieve an accurate level position with the leveling ring in the vessel. There is also room for a small bubble level between slots for verification purposes.
The PAV3 includes a network-ready modem, which provides connection to the internet, permitting the user to access the PAV3 with a mobile device or PC using a VNC viewer app program. VNC connection enables the user to connect, monitor, and control the PAV3 from a remote location. The PAV3 can be programmed with a custom IP address, so the number of PAV3s on a single network is essentially endless.
