The core working principle of the rapid flash point tester is based on the flammability of liquid vapor, which achieves accurate determination of flash point through three key steps: heating, ignition, and detection. The technical principle is as follows:
1、 Core working principle
Sample heating and temperature control
The instrument adopts a three-stage temperature control program: the initial stage rapidly heats up at 5-6 ℃/min, the middle stage precisely controls the temperature to 1.0-1.5 ℃/min, and the critical stage gradually heats up to 2.5-3.5 ℃/min. This design ensures a uniform increase in sample temperature and avoids measurement errors caused by local overheating.
Automatic ignition and flash detection
When the temperature approaches the expected flash point, the electric ignition device triggers ignition every 1 ℃, periodically igniting near the sample surface through electric sparks or flames. K-type thermocouples monitor flame propagation in real-time, capture instantaneous flash phenomena, and ensure detection sensitivity.
Result determination and data locking
The system automatically recognizes the flash temperature and locks the data, while correcting the impact of environmental factors on the results through PT100 temperature sensors and high-sensitivity barometers to ensure testing accuracy of ± 0.5 ℃.
2、 Highlights of Technological Innovation
Full process automation
From sample heating, ignition to result output, there is no need for manual intervention throughout the entire process. The one click start function combined with fast cooling technology shortens the single detection time to within 30 minutes, increases the daily processing capacity to 20-30 samples, and improves efficiency by more than 50% compared to traditional methods.
Intelligent security design
The dual protection system (6.4mm thick air bath insulation layer+automatic cooling fan) and emergency protection mechanism (automatic power-off and lid opening interruption test for overheating) ensure safe operation. The fully enclosed testing chamber avoids steam leakage and meets explosion-proof standards.
Digital management and cloud platform integration
Support electronic data storage, traceable testing records, and remote monitoring on cloud platforms. The 7-inch high-definition touch screen displays temperature curves in real-time, and data can be transmitted via USB or wireless for trend analysis and compliance management.
