FY-3536Y liquid display automatic Cleveland flash point instrument

FY-3536Y liquid display automatic Cleveland flash point instrument is a professional instrument for determining the flash point and ignition point of petroleum products. The following is a related introduction:

Working principle

Based on the Cleveland open cup method, the sample is placed in the Cleveland open cup and heated at a specified heating rate. During the heating process, the sample continuously evaporates to produce vapor. When the mixed gas formed by the sample vapor and the surrounding air reaches a certain concentration, a flash fire will occur when it contacts the specified ignition source. The lowest temperature at this time is the flash point. Continue heating. When the sample contacts the flame and can continue to burn for no less than 5 seconds, the lowest temperature is the ignition point.

Instrument features

High degree of automation: It adopts a fully automatic design, which can automatically complete operations such as sweeping, testing, and data printing. The test arm can automatically rise and fall, reducing the error and workload of manual operation.
Intuitive display: Equipped with a liquid display screen, it can clearly display test data such as temperature, which is convenient for operators to read and record.
Precise temperature control: High-precision temperature sensors and advanced temperature control technology are usually used to accurately control the heating rate, ensure that the heating process meets the requirements of relevant standards, and make the test results more accurate.
Good safety performance: Generally, it has a variety of safety protection functions, such as overheating protection, leakage protection, etc., which can effectively prevent safety accidents during the operation of the instrument.
Easy operation: All-Chinese human-computer dialogue interface, no logo keyboard, with menu prompts, guided input functions, operators can easily set parameters and test operations.
Strong data processing function: It can automatically record and store test data, and some can also perform data statistical analysis, print test reports, etc., which is convenient for users to manage and trace test results.

Technical parameters

Working power supply: AC 220V±10%, 50Hz.
Heating device: Generally uses quartz tube electric furnace for heating, no open flame, explosion-proof, power 0~600W continuously adjustable.
