Open Cup Flash Point Tester with Dual Fire Suppression
Open Cup Flash Point Tester with Dual Fire Suppression – ToronFPT™ OC-DS
ToronFPT™ OC-DS is a full-automatic open cup flash point tester designed and manufactured in accordance with ASTM D3536 and ASTM D92 standards for flash point testing and ignition point determination of petroleum products, lubricating oils, and other flammable liquids. As a high-automation flash point tester, the ToronFPT™ OC-DS performs fully automatic temperature control, automatic lid operation, automatic measurement, automatic printing, and automatic flame detection — while incorporating covering fire extinguishing plus inert gas spray fire extinguishing for superior safety compared to conventional automatic open cup flash point testers.
The ToronFPT™ OC-DS flash point tester addresses the critical fire risks associated with traditional manual and semi-automatic flash point testers — where operational uncertainties and manual firefighting after ignition can severely damage equipment and pose safety hazards. Featuring a silicon nitride automatic ignition head with smart flame detection and automatic re-ignition, the instrument delivers long-lasting, reliable ignition performance without manual gas gun operation.

- Chemical and petrochemical industry: flash point screening for process safety and transportation hazard classification
Applicable Standards
The ToronFPT™ OC-DS open cup flash point tester is designed to support testing in compliance with the following international standards:
ASTM D92 is a standard test method that covers the determination of the flash and fire points of petroleum products (excluding fuel oils) using a Cleveland open-cup tester.
Open Cup Flash Point Tester with Dual Fire Suppression – ToronFPT™ OC-DS Key Features
The ToronFPT™ OC-DS automatic open cup flash point tester delivers an advanced feature set for safe, accurate, and fully automated flash point testing:
- 8-Inch Full HD Color LCD Touchscreen Interface: the instrument features an 8-inch color HD LCD touch screen with all human computer dialogue interface for intuitive, straightforward operation.
- Preset Parameters and Delayed Temperature Start: temperature, sample name, delayed temperature initiation, and other parameters can be preset for hands-off test startup, enabling batch test preparation.
- Real-Time Temperature and Time Function Curve Display: accurate simulation tracking provides real-time display of temperature and test time function curves, with software prompt function for misoperation modification.
- Atmospheric Pressure Correction: the instrument comes with an atmospheric pressure sensor to automatically correct the influence of atmospheric pressure on flash point test results — a requirement of ASTM D92 for accurate, site-independent flash point determination.
- Silicon Nitride Ignition Head with Auto Re-Ignition: silicon nitride automatic ignition head eliminates the need to manually operate gas guns. Electric and gas ignition can be freely switched. Smart flame detection with automatic re-ignition greatly extends the service life of the ignition head.
- Automatic Rotating Lift Arm: automatic rotating lift arm with lifting, scanning, detection, and printing functions makes the entire measurement process fully automatic and operationally complete.
- Intelligent Sample Cup Cooling Rack: the forced cooling system quickly cools the heating system. The intelligent sample cup cooling rack automatically starts and stops the cooling system based on sample cup temperature, allowing the next test to begin within 10 minutes.
- Dual Fire Protection System: double fire protection with hidden lift type dual fire extinguisher: the instrument actively detects the open fire and automatically extinguishes it within two seconds by deploying covering fire extinguishing and inert gas spray fire extinguishing in sequence.
- LIMS Connectivity via USB Port: the LIMS system can be connected through the USB port for seamless integration into laboratory data management environments.
Theory and Method
The ToronFPT™ OC-DS measures flash point using the Cleveland Open Cup (COC) method as specified in ASTM D92. The petroleum sample is placed in the open test cup, and the instrument automatically controls the heating rate through three programmable stages, raising the sample temperature at a precisely controlled rate. As the sample approaches the expected flash point, the ignition source (a switchable electric/gas ignition system with automatic gas gun ignition) passes over the cup surface at defined intervals.
Flash point is detected when a flash appears above the sample surface and is immediately identified by the instrument's smart flame detection system. An atmospheric pressure sensor automatically corrects the measured flash point value for the influence of atmospheric pressure on the test result, as required by ASTM D92. Upon flash detection, the dual fire protection system activates covering fire extinguishing is deployed first, followed by inert gas spray fire extinguishing if needed ensuring that the open fire is extinguished within two seconds of occurrence. The forced air cooling system then rapidly cools the test cup and heating system to below ambient temperature, allowing the next test to begin within 10 minutes.
