This instrument is in accordance with the industry standards of the People's Republic of China SH/T 0308《 If the lubricating oil air release value is required, it is suitable for SH/T 0308 The test method specified in the standard determines the ability of lubricating oil to separate mist air - to determine the air release value of petroleum products such as hydraulic oil and turbine oil. This instrument can be used in chemical, electric power, petroleum and other industries to determine the air release value of petroleum products such as hydraulic oil, steam turbine oil, etc.

1. Main technical characteristics

1、It uses a high-precision digital thermostat and a high-precision temperature sensor to control the temperature of the water bath and air bath.

2、use PID Temperature control system, self-tuning and four-digit dual LED The window indicator function is digitally displayed, the temperature can be continuously adjusted, the temperature can be controlled quickly, the response is fast, the overshoot is small, and the temperature control accuracy is high.

3、It is equipped with a timer to automatically time, and the air circuit is automatically cut off when the time is time.

4、A magnetic circulation pump is used as a water bath circulation stirring device to ensure that the water flow outside the test tube is automatically circulated.
