The KDBS-305D automatic closed flash point tester is used to determine the closed flash point value of petroleum products. Adopting a liquid crystal TET pure color touch screen and a human-machine dialogue interface, it has a prompt menu prompt input for parameters such as temperature, oil test grade, atmospheric pressure, and test date, which is convenient and fast. It is an open and fuzzy control integrated software with a modular structure, widely used in railway, aviation, power, petroleum industries, and scientific research departments.

 
Closed flash point automatic tester with multi furnace function and unordered access function: adopting modular design, one host can simultaneously control multiple testing furnaces and test different samples simultaneously or in a timed manner. The testing furnace interface can be connected to the host without any serial number.

 
The Binsky Martin closed cup method is used to determine the flash point of flammable liquids, liquids with suspended particles, liquids that tend to form a film on the surface under test conditions, and other liquids. Suitable for samples with a flash point higher than 40 ℃. Not suitable for liquids containing water-based paints or highly volatile materials.

1. Multi furnace function of one machine: adopting modular design, one host can control multiple testing furnaces at the same time, and can test different samples simultaneously or in a time-sharing manner;
2. Unordered access function: The test furnace interface can be connected to the host without any serial number, and the host automatically recognizes the connected test furnace number. The host reserves three access ports, and the number of access ports can be increased according to user needs;
3. Adopting high-speed signal processor control and high-precision analog/digital conversion circuit, the instrument works reliably and has high testing accuracy;
4. No gas source electric ignition method, automatic ignition;
5. Built in atmospheric pressure sensor, automatic measurement and calibration of atmospheric pressure results;
6. Adopting adaptive PID control algorithm to automatically adjust the heating curve according to standard requirements;
7. Heating up, opening the lid, ignition, alarm, cooling, printing, the entire experimental process is automatically completed;
8. Equipped with automatic fault detection and alarm function. When there is a sensor malfunction, oil sample error, or excessive temperature, the instrument will automatically stop testing and sound an alarm;
9. Built in high-speed thermal micro printer, with beautiful and fast printing, and offline printing function;
10. Historical records with time stamps, up to 255 can be stored;
11. 320 × 240 dot matrix graphic LCD display screen, operated by touch screen, with screen protection function, extending the service life of LCD;
12. Equipped with a standard RC232 interface, it can be connected to a computer for easy processing of test data;
