PCB309A intelligent low temperature closed flash point tester
General description
Our company produces the "PCB309A intelligent low temperature closed flash point tester (hereinafter referred to as instrument), according to the" Peoples Republic of China national standard - Determination of flash point, binski - Martin closed cup method -GB/T 261-2008 "and ASTM D93.C, ISO22719-2002 and other related provisions, the microprocessor control technology combined with color LCD touch display system is designed. The instrument is used to determine the flash point of a liquid sample. The ASTM D93.C standard is added to the test program for different users. The requirements for measuring low temperature flash points such as biodiesel have been met.Optional 232 computer management interface (set of device computer software)
Features
in the English bilingual menu, true color GUI touch screen interface design, intuitive and simple operation (not to read the instructions can be quickly familiar with the operation process can be under certain conditions), the instrument of reasonable structure, high testing speed, wide measurement range, good repeatability and validity etc.. The testing process of the instrument is automatic, and the parameters of temperature and time are all displayed by LCD. On this LCD screen, users will also see the working state of the instrument and related operation hints at the same time.
You only need to preset the expected flash point or the starting temperature of the material to be tested. The instrument can start the refrigeration and heating up according to the prescribed rate, then ignition, flash point detection, detection device upgrading, air cooling, printing and output are sequentially carried out. It relieves the past complex operation process which must be hands-on, and has the function of automatic detection and manual input of atmospheric pressure. When the state of automatic detection is effective, manual input is invalid, and vice versa. The instrument will automatically modify the test results according to the change of atmospheric pressure.
The instrument has a powerful data processing function: it can memorize the previous 100 analysis results to facilitate your inquiry and printing of historical records. It can memorize the preset parameters before each shutdown.
The instrument contains a hundred year calendar, which can show year, month, day, time, minute and second.
Instrument structure
The instrument is designed for a single body with beautiful shape, compact structure, light weight and small volume.
The super large scale control core is equipped with power supply, interface, clock, drive, liquid crystal display system and other functional circuits, as well as electric heating furnace, opening mechanism, detection mechanism, gas source control valve and lifting mechanism and other executive components to complete the automatic control of the whole process.
The whole instrument has many advantages, such as compact structure, simple operation, accurate measurement, reliable operation, small volume and light weight. It is widely used in petrochemical, electric power, railway and scientific research departments. It is a special device for testing various kinds of oil flash points in laboratories and laboratory.
