– Intelligent, Safe, and Accurate for Flash Point Testing of Petroleum Products
In the petroleum, chemical, power generation, fuel storage, and quality inspection industries, closed cup flash point is a key indicator for evaluating the flammability, safety, and volatility characteristics of oil products. The DFYF-111Z Fully Automatic Closed Cup Flash Point Tester is designed and manufactured in strict accordance with GB/T 261 and ASTM D93 standards. It is suitable for flash point determination of diesel, gasoline, kerosene, lubricating oils, solvent oils, and various petroleum products – making it an ideal choice for safety testing in both laboratory and industrial settings.
1. Standard Compliance and Applicable Samples
The DFYF-111Z complies with the following international and national standards:
GB/T 261 (Pensky-Martens Closed Cup Method)
ASTM D93 (Pensky-Martens Closed Cup Method)
Applicable sample types:
Diesel, kerosene, fuel oils
Lubricating oils and greases
Solvent oils, paints, and chemicals
Various petroleum products and flammable liquids
This method is globally recognized for flash point determination and is widely used in refineries, quality inspection agencies, aviation companies, power utilities, and third-party laboratories.
2. Key Technical Specifications

3. Performance Features
3.1 Fully Automatic Intelligent Operation
The instrument utilizes advanced microcontroller technology for a high degree of automation. The user simply sets the expected flash point value and presses "Start". The instrument then automatically completes the entire process:
Heats according to the standard ramp rate
Automatically ignites
Automatically detects the flash point
Automatically determines the end of the test
Automatically prints the test results
3.2 7-Inch Color Touch Screen
Equipped with a 7-inch color LCD touch screen, the interface is intuitive and user-friendly. Parameter setting and result review are quick and convenient.
3.3 Automatic Cooling System
After the test is completed, the instrument automatically activates a cooling fan to rapidly reduce the temperature of the heating assembly – reducing wait time between tests and improving laboratory efficiency.
3.4 Automatic Atmospheric Pressure Correction
The instrument automatically detects atmospheric pressure and applies real-time correction to flash point results, ensuring accurate and comparable test data regardless of altitude or weather conditions.
3.5 Fault Self-Diagnosis and Alarm
If the instrument detects an abnormality or malfunction, the system automatically triggers an audible/visual alarm, allowing operators to take timely action – protecting both equipment and personnel.
3.6 Built-In Gas Supply – No External Source Required
The instrument comes with a built-in gas supply, eliminating the need for users to purchase or install external ignition gas cylinders – simplifying installation and maintenance.
4. Comparison with Traditional Manual Flash Point Testers
Feature | Traditional Manual Closed Cup Tester | DFYF-111Z Fully Automatic |
Operation | Manual ignition, manual observation | Fully automatic + touch screen control |
Cooling method | Natural cooling, long wait time | Automatic fan cooling, high efficiency |
Atmospheric pressure correction | Manual table lookup | Automatic detection and correction |
Fault indication | None or simple indicator light | Automatic alarm |
Data storage | Handwritten records | Stores 200 results, searchable |
Gas supply | User-supplied | Built-in, no external source needed |
Result printing | Manual transcription | Automatic printing |
5. Typical Applications
