1. Oil is an important energy source. From petroleum extraction, transportation, refining, sales, and use, petroleum testing instruments are needed to assess the performance and quality of petroleum and petroleum products.

2. In developed countries, commonly used petroleum instruments, such as flash point, distillation, viscosity, condensation point, pour point, cold filter point, etc., are automatically controlled by a computer to automatically detect and print. With the rapid development of China's economy, petroleum testing instruments have gradually evolved from manual instruments to automatic instruments in recent years.

3. After more than ten years of hard work, our company's automatic oil equipment, especially the "low-temperature automatic petroleum instrument", has invented five national patents for aluminum block cold traps, low temperature temperature jumps, and multiple cold trap scanning refrigeration. It is the core technologies such as optical fiber detection and programmable control that have helped our company's automatic petroleum equipment reach the highest level in the country. Compared with foreign companies' branded products, it is no less. Especially for the automatic detection of crude oil viscosity, freezing point, pour point, better than other companies.

4, automatic viscosity tester, our company has its own distinctive features.

- The automatic instrument adopts the ordinary standard Pines, Countercurrent, Uhler, and Langeglass viscometers, which can be easily disassembled and replaced, and can be easily sent to the metrology department for identification.

- Automatic detection of optical fibers (patent number: ZL01212191.6)

- The viscometer is automatically cleaned and dried.

- Microprocessor control, touch screen, printer and computer communication - 1 slot, 4 slots, 2 slots, and a variety of working methods.

5. Determination of the solidifying point of crude oil (including black heavy oil) According to GB/T510 and GB/T2538 standards, the automatic instrument manufactured by the company can automatically cool the temperature, and the aluminum block cold trap automatically tilts 45o, and the optical fiber is automatically detected ( Patent No.: ZL200420070208.2) The technical level of the whole machine has reached the highest level in the country and it is one of the company's top-quality products (lighter oil is more detectable).

6. The pour point of the petroleum products and the determination of the cold filter points all require the instrument refrigeration system. Within 2.5 minutes, the temperature of the cold trap drops suddenly by 17°C, such as 0°C → -17°C → -34°C → -51°C → -68°C .
