TP661 Air Release Value Tester
Product Introduction
The TP661 Air Release Value Tester is designed according to SH/T 0308-92, Test Method for Air Release Value of Lubricating Oils, and is used to determine the air release value of hydraulic oils, turbine oils and other petroleum products.
The petroleum products air release value tester integrates air and water bath temperature control with air pressure control. It uses computer-based dual-channel temperature control and PID temperature regulation to provide stable and accurate testing conditions. The TP661 is suitable for quality control, product evaluation and research in the petroleum, chemical and power industries.

Performance Features
• SH/T 0308-92 compliant: Designed for air release value testing according to the specified test method.
• Dual-temperature control: Simultaneously and precisely controls air and water temperatures.
• Integrated control system: Combines air temperature, water bath temperature and air pressure control.
• PID temperature control: Provides accurate and stable temperature regulation.
• Oil-free silent pump: Produces a stable airflow with low operating noise.
• Stable and reliable performance: Provides accurate results and good repeatability.
• Automatic liquid-level detection: Helps prevent instrument damage caused by insufficient water level.
• LCD display: Provides convenient observation of test parameters and operating status.

Working Principle
The TP661 air release value tester operates according to SH/T 0308-92. During the test, air is introduced into the petroleum product sample under specified temperature and pressure conditions. Air bubbles dispersed in the oil gradually escape from the sample.
The instrument precisely controls the air temperature, water bath temperature and air pressure to establish stable test conditions. After the specified test process, the time required for the entrained air to be released is evaluated according to the applicable test method, providing the air release value of the tested oil.
The combination of PID temperature control, stable airflow and accurate pressure adjustment helps improve test repeatability and measurement reliability.
