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 HTBS-800 fully automatic closed cup flash point tester is manufactured in accordance with the new standard method 1 of the national standard GB/T261-2021 “Determination of Flash Point – Pensky-Marten Closed Cup Method” and the provisions of ASTMD93. It is applied in the petroleum, chemical, power, environmental protection, railway, scientific research and other departments, and is an ideal instrument for closed cup flash point testing.

Main features 

1. It adopts a new type of 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 automatically measures, corrects and corrects the flash point value of atmospheric pressure；
3. The automatic measurement of lifting, stirring, ignition, detection, alarm, cooling and printing instruments is completed；
4. Safe and gas-free, platinum alloy electric heating wire ignition method, safe, stable and reliable, with high testing accuracy；
