Comprehensive Selection of Flash Point Detection
Date: 2020-4-24

Flash point refers to the lowest temperature at which the steam volatilized by combustible liquid can flash and start fires when meeting the fire source after mixing with air to form combustible mixture and reaching a certain concentration. Under this temperature, it removes the fire source and the combustion which cannot be sustained. In oil products, generally speaking, flash point refers to the lowest temperature, expressed in ℃, that can cause flash fire on the oil surface under the specified heating conditions and at a certain interval across the mixture of steam and air escaping from the heated oil products with a flame.

The flash point is mainly used as the safety index to be considered in the storage, transportation and use of liquid oil products, judging whether the oil components are polluted and to measure whether the product specifications meet the requirements. The detection of flash point can be divided into closed cup method and open cup method according to the product properties and service conditions. The closed flash point tester is mainly used for light petroleum products with high evaporation, such as transformer oils, fuel oils, etc. The open flash point tester is mainly used for lubricating oil and heavy petroleum products. Because in the measurement of open flash point, the vapor formed by heating petroleum products continuously diffuses to the surrounding air, making the measured flash point on the high side. For most lubricating oils and heavy oils, especially when it is used under the condition of unsealed parts or low temperature, thus even if there is a very small amount of light mixture, it will evaporate in the process which will not constitute the risk of fire or explosion. All of them are determined by open cup flash point method.

Panan has many products that can meet your needs in flash point detection:

Austria's Eralytics micro closed cup flash point instrument ERAFLASH, is in compliance with ASTM D6450, D7094, and SH/T 0768. The ERAFLASH flash point meter adopts the continuous closed cup flash point method and only needs 1-2ml sample to complete the test. The ERAFLASH flash point meter adopts the patented PBT semiconductor temperature control technology, which greatly accelerates the cooling and heating rate within the temperature range of - 25 ℃ ~ 420 ℃. At the same time, the ERAFLASH flash point meter can be equipped with a low-temperature module to expand the temperature range from - 40 ℃ ~ 420 ℃.

 

Japanese brand Tanaka scientific flash point tester of various types

 

1) The abl-8 Abel closed cup flash point tester meets the requirements of GB / T 21789, IP170, ISO 13736, ISO 1516, ISO 1523, and the test temperature range: - 30 ℃ ~ 70 ℃. The abl-8 Abel closed cup flash point tester assembles the detection sensor, temperature sensor and mixing blade on the test rocker arm, which allows adding the sample becomes more convenient. Abel flash point instrument has automation functions and multiple self-protection functions to ensure the safety of the testing process. Abel has a variety of built-in test modes which can also customize test conditions according to certain needs in order to meet the requirements of routine testing and scientific research testing.
