Fully automatic closed flash point tester

The fully automatic closed flash point tester is mainly used for measuring the closed flash point value of petroleum products. The instrument adopts ARM microprocessor technology, 7-inch color touch screen technology, and Chinese menu, making human-computer interaction more convenient; The instrument has a power-off storage function; The instrument has functions such as automatic ignition, display, locking and printing results, automatic cooling, etc; The instrument has the advantages of accurate measurement, good repeatability, stable and reliable performance, and simple operation. Widely used in departments such as power, petroleum, chemical, commercial inspection, and scientific research, it meets the requirements of ASTM D93 and GB/T 261-2008 standard methods.

Instrument features:

1. The display adopts an original imported 7.0-inch true color TFT-LCD display screen; The keyboard adopts a human body sensing touch screen. Full Chinese operation interface, display delicate, intuitive and generous, easy to operate, and touch freely.

2. Historical data storage adopts NVM data storage, which can store 20000 historical data. The data can be saved for 10 years without loss and cannot be changed.

3. The printer adopts a miniature embedded thermal printer, which can print quietly, quickly, and clearly.

4. The temperature measurement and control adopts the original imported PT100 platinum resistance temperature sensor, high-precision AD converter, excellent linear mathematical model, and unique control algorithm, making the temperature measurement and control faster, more accurate, and more stable.

5. The ignition adopts electronic flame direct ignition, which is completely the same as gas flame ignition, safe, convenient, fast, reliable, and non-interference.

6. Flash fire detection adopts high-frequency ion ring flame detection technology, which enables the sample to quickly and accurately capture flash fire, avoiding false positives and missed detections.

7. The atmospheric pressure measurement adopts a fully digital atmospheric pressure sensor imported from Germany, which measures the local atmospheric pressure in real time and automatically corrects the impact of atmospheric pressure changes on the measurement data.

8. Automatically complete heating, detection, calculation, printing and other operations.

9. The instrument is heated according to the temperature rise curve specified in ASTM D93 and GB/T261-2008 methods. When the temperature approaches the flash point value, it will automatically ignite. When a flash point occurs, the instrument will automatically lock and display the printed result, while automatically cooling the heater.
