Under specified conditions, when the oil is heated to a certain temperature, the mixture of oil vapor and surrounding air will flash upon contact with the flame. The lowest flash temperature is called the flash point value of the oil.
The KR-CPF80 fully automatic closed flash point tester is manufactured in accordance with the new standard method 1 of the national standard GB/T261-2021 “Determination of Flash Point by Binsky Martin Closed Cup Method” and the requirements of ASTMD93. It is applied in departments such as petroleum, chemical, power, environmental protection, railway, and scientific research, and is an ideal instrument for conducting closed flash point testing
Main features:
- Adopting a new high-speed signal processor control, adaptive PID control algorithm, automatically adjusting the heating curve according to standard requirements.
- Equipped with an automatic atmospheric pressure detection chip, atmospheric pressure is automatically measured, calibrated, and the flash point value is automatically corrected.
