Overview
Closed flash point tester, it is used to measure the closed flash point value of petroleum products. It adopts foreign advanced technology, liquid crystal tet pure color touch screen, full Chinese display man-machine dialogue interface, prompt menu prompt input for parameters such as preset temperature, oil test mark, atmospheric pressure, test date, etc., which is convenient and fast. It is open, fuzzy control integrated software, modular structure, and conforms to GB / T261-2008 and GB / T261-83 Determination of Flash Point - Pensky-Martens closed cup method and ASTM D93 Standard Test Methods for Flash Point by Pensky-Martens Closed Cup Tester . It is an ideal substitute for imported instruments. It is widely used in railway, aviation, electric power, petroleum industry and scientific research department.
Advantage
1. It has the function of prompt modification of Chinese misoperation software;
2. Equipped with test date, test time and other parameters prompt function;
3. The influence of atmospheric pressure on the test is corrected automatically and the corrected value is calculated;
4. Differential detection, automatic correction of system deviation;
5. Cover opening, ignition, detection and printing data are completed automatically;
6. The test arm rises and falls automatically;
7. Ignition mode: electronic ignition. Forced air cooling.
Working principle:
Under the conditions specified in the national standard, the sample is put into the test cup, and the test cup containing the test oil is heated. The minimum temperature of the mixture gas formed by the petroleum vapor and the surrounding air is taken as the flash point when it contacts with the flame.
According to the collected temperature changes, the computer sends out instructions from the I / O port to control the heater to make the temperature of the test oil rise at a certain rate. The scanning cycle, ignition time, differential detection and automatic control are implemented. When the flash fire is detected, the computer system stops data collection, displays the flash temperature and prints the record results, stops heating, turns off the flame, and starts forced air cooling.
