SH0308B Air Release Value Tester
The SH0308B air release value measuring instrument adopts advanced
32-bit MCU and 7-inch large screen LCD display, which has the
advantages of stability, reliability, easy operation, and
maintenance. Applicable to SHT 0308-1992 "Method for determination
of air release value of lubricating oil". Built in pressure
controller, automatically controls air pressure without manual
adjustment. Complies with ASTM D3427-2007 for measuring the air
release value of lubricating oil.
Main functions and features
● A 4-inch high-resolution color touch screen with a resolution of
1024 × 600, featuring simple and easy-to-use human-computer
interaction.
