SH105D low temperature balance closed flash point apparatus operation specification
1. Open the cooling circulation device.
2. Put the lid on the cup.
3, open the gas adjustment knob, ignite the test flame, and adjust the flame into a ball, the diameter is 3.5±0.5mm.
4. When the instrument reaches the preset temperature and alarms, use a dry and clean syringe to absorb 2ml sample, quickly inject the sample into the sample groove through the feeding hole, pay attention to not make any loss of the sample; Pull out the syringe and the instrument starts timing automatically.
5. After 60 seconds of automatic countdown of the instrument, the skateboard should be opened immediately, and the flame nozzle should be extended and removed to complete a ignition test with a time of 2.5±0.5s. Meanwhile, the flash fire of the skateboard from opening to closing should be observed.
6, if there is no flash, repeat the above process according to the requirements of the test method until the flash; After the flash occurs, the instrument automatically detects and prints the result. The experiment is over.
SH105D balance method low temperature closed flash point meter is designed and manufactured in accordance with the requirements of the People's Republic of China standard GB/T 5208 "Flash point determination fast balance closed cup method". The instrument also meets the requirements of ISO 1523 and ISO 3679 standards.
The instrument with advanced electronic temperature control instrument as the core, equipped with appropriate interface circuit, realize the automation of temperature control, with automatic heating power switch, automatic temperature control and other functions. The instrument is simple in operation, reasonable in structure, accurate in detection, stable in performance and intuitive in display. It is an ideal substitute for imported instruments and can meet the requirements of petroleum, chemical industry, coating, paint, railway, aviation, electric power, commodity inspection and scientific research institutes for rapid testing of the flash point of petroleum products.
The instrument is especially suitable for the test of the flash point of the closed cup of all kinds of paints, paints, adhesives, solvents, petroleum and related products within the range of -30℃ ~ +100℃.
