This instrument is manufactured in accordance with the requirements specified in the national standard SH/T 0308 “Test Method for Air Release Value of Lubricating Oils”. It is used to determine the ability of lubricating oils to separate entrained air bubbles — to measure the air release value of petroleum products such as hydraulic oils and turbine oils; and is applicable to industries such as chemical engineering, electric power, and petroleum.

Main features:

1. Adopting microcomputer processing and PID self-tuning technology

2. Precisely control two temperature channels simultaneously, integrating temperature control, air management, and constant temperature functions

3. It overcomes the problem of poor experimental results caused by inconsistent temperatures of water baths, air, and densimeters in similar products.

4. It adopts a blue LCD display, with a Chinese menu, man-machine dialogue, and simple operation.

5. Advantages such as stable performance, accurate data, and good repeatability.
