1. The old model uses a 320x240 large-screen graphic LCD display, and the new model uses a 640x480 color touch screen.
2. The test furnace can be expanded for the old model, but not for the new model (not expanded in actual applications)
3. The old platinum heating wire or gas ignition method is optional, the new platinum heating wire method (the gas ignition method is not used in practical applications)
4. Store up to 255 historical records of the old model, and store up to 50 historical records of the new model
5. Compared with the old model, the temperature control range of the new model is unchanged, and the temperature measurement range is larger.
6. The old flash fire sensor: ion detection ring; the new flash fire detection: K-type thermocouple
7. The screw of the new model is stronger than the old model, and the rising height is higher than before
8. The operation interface is optimized, self-checking function is added, and test standards are increased
9. The deviation between the desired flash value and the actual flash point value during the test of the old model is more than 5 ℃ before the test can be performed. The new test process will have a prompt if the deviation between the desired flash value and the actual flash point value is more than 5 ℃ but does not affect the test.
