A2004 Automatic Vacuum Distillation Tester is a specialized instrument used to detect the boiling point of partially or completely evaporated petroleum products. This instrument uses a microcontroller as the system control core, a color LCD display screen, a Chinese menu human-machine dialogue, guided operation, and a high degree of automation in the measurement process. According to the measurement requirements, set the constant temperature and required pressure reduction for the circulating cooling water and receiving chamber, control the distillation speed and constant steam pressure reduction, cooling circulating water temperature, and receiving chamber temperature.

Standards：GB9168-1997、ASTM D1160

Instrument characteristics

1. Intelligent heating management system ensures that the distillation rate meets the requirements of the experimental method.

Record the user's own settings:

Users can record the recovery volume corresponding to the temperature

Users can record the temperature corresponding to the recycling volume

Users can record the record points specified in the national standard

Five ways to end the experiment:

① End point: End the experiment at the final boiling point

② End of task: End the experiment at the task point

③ Temperature End: End the experiment according to the temperature value requested by the user and print out the output.

④ Volume End: End the experiment based on the volume value set by the user and print out the output.

2. Equipped with an internal clock, no need to input the experiment date, with an effective lifespan of 95 years.
