This instrument meets the requirements specified in the national standard SH/T 0308 “Determination Method for Air Release Value of Lubricating Oils”. It is used to determine the ability of lubricating oils to separate entrained air – specifically measuring 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. Controlled by an STM microprocessing chip with an adaptive PID control algorithm, it automatically adjusts the heating curve according to standard requirements;

2. 8-inch Chinese-English color touch screen for display and operation, with a temperature control accuracy of ±0.1℃;

3. The instrument has a built-in large-capacity air pump, eliminating the need for an external air source. It features micro-adjustment and correction of air pressure, with a pressure adjustment range of 0-0.2Mpa;

4. A dedicated air constant temperature device to overcome the problem of inconsistent experimental results caused by temperature differences between the water bath, air, and densimeter;

5. Precise control of two temperature channels, integrating temperature control, air supply, and constant temperature functions;

6. Automatic water shortage alarm and automatic water replenishment function for the water bath to prevent damage to the heating device due to dry burning;

7. Display and operation in multiple languages. When national standards are revised, the instrument program can be upgraded;
