Under specified conditions, when the oil is heated and its temperature reaches a certain level, the mixture of the oil’s vapor and the surrounding air will flash when it comes into contact with a flame. The lowest flash temperature is called the flash point value of the oil.

The HTBK-800 fully automatic open flash point and fire point tester is manufactured in accordance with the standard methods of GB267 “Determination of Flash Point and Fire Point of Petroleum Products (Open Cup Method)” and GB3536 “Determination of Flash Point and Fire Point of Petroleum Products (Cleveland Open Cup Method)”. It is an ideal instrument for open flash point testing in departments such as petroleum, chemical engineering, power, environmental protection, railways, and scientific research.

Main features：

1. It adopts a high-speed signal processor for control and an adaptive PID control algorithm to automatically adjust the temperature rise curve according to standard requirements；
2. It is equipped with an automatic atmospheric pressure detection chip, which can automatically measure, correct and adjust the flash point value of atmospheric pressure；
3. Data storage function, capable of storing 1000 results, and historical records can be accessed at any time；
4. Differential detection, automatic correction of system deviation, automatic stop of detection and alarm when temperature exceeds the limit；
5. The ignition, detection, alarm, cooling and printing instruments automatically complete the measurement；
6. Safe and gas-free, platinum alloy electric heating wire ignition method, safe, stable and reliable, with high testing accuracy；
7. Both Chinese and English interfaces are available for operation. When national standards are revised, the instrument program can be upgraded；
8. The optional USB interface can export data to a computer (optional), and the RS485 port communicates with the user
9. It comes with 12 sets of data temperature point corrections
10. The furnace body temperature is automatically displayed, allowing you to check it at any time for convenient sample making next time
11. It is equipped with an exhaust interface. After the test is completed, the power of the fume hood will be automatically connected and the exhaust function will be activated
12. It can be externally connected to a closed-mouth furnace body to achieve simultaneous measurement of open and closed mouths
13. The automatic temperature and humidity sensing function can display the laboratory environment in real time
14. The password classification management system enables the superior control to conduct technical sub-division control over the instruments
