1. The crude oil vapor pressure tester is designed and manufactured according to the national standard GB/T 11059-2011- Determination of Crude Oil Vapor Pressure - Expansion Method. It is an equipment for measuring the vapor pressure of crude oil and is widely used in petroleum, chemical, scientific research, metrology and other departments.

2. The core host adopts TI's AM3354 processor, Cortex-A8 core, and a 1GHz clock speed; The operating system adopts Windows Embedded Compact 7 real-time industrial control system. Completely abandoning the use of non nuclear and non operational single-chip microcontrollers, truly realizing the modernization of instrument control and ushering instruments into a new era of intelligence.

3. Historical data storage adopts FLASH data storage, which can store 2010 historical data, and the stored data cannot be changed.

4. The printer adopts a micro embedded thermal printer, which prints quieter, faster, and clearer; Customized needle printers can also be used, and the printed results can be stored for a long time without fading.

5. The monitor adopts the original 7.0-inch 800 × 480 pixel true color TFT-LCD LCD screen from Innolux, with a fully Chinese operation interface and delicate, intuitive and generous display.

6. The operation adopts a capacitive touch screen, which has the advantages of no mechanical loss, dust and water resistance, resistance to radio frequency interference, and long service life.

7. Configure a USB interface for later software updates and can also be connected to a mouse for precise operation.

8. The temperature detection adopts the original imported PT100 platinum resistance temperature sensor, combined with a high-precision AD converter, and controls the electric heating tube through excellent linear mathematical models and unique control algorithms, making temperature measurement and control faster, more accurate, and stable.

9. It has the function of setting parameter storage. After power failure, it can be restarted to maintain the previous parameter settings.

10. Piston type pressure transmitter, with stable structure, accurate measurement, and real-time response to indoor pressure measurement.

11. Adopting imported pressure transmission core, with excellent performance, stability, and long service life.

12. The instrument is equipped with high-precision injection and discharge valves, independently designed and manufactured by our company, driven by high torque precision motors, perfectly solving the impact of leakage and excess volume on test results.

13. The instrument measurement room is equipped with a vibration mechanism, which oscillates the measurement room during the test process to ensure that the tested sample evaporates fully and accurately measures the vapor pressure of the sample.

14. The instrument testing process is fully automated, without the need for human observation. The instrument automatically completes steps such as injection, expansion, oscillation, temperature control, detection, and layout. At the end of the experiment, the instrument will automatically print the test results, greatly freeing up the hands of laboratory operators.
