Now available from Particle Test , the automated Cleveland Open Cup flash point tester accurately determines flash and fire point temperatures of viscous petroleum products over an extended temperature range.
When examining highly viscous specimens, such as oils and bitumens, a preheating time and temperature are set in order to liquefy the sample for flash point testing.
The flash point tests are simply conducted by mounting the flash cup filled with sample into the test position and selecting a pre-programmed test method or the search mode to determine an approximate flash point. The flash point test results are automatically corrected to standard pressure (101.3 kPa).
Equipped with a differential Pt-100 RTD probe, the Clevelabd Open Cup flash point tester is designed to duplicate the response time of a mercury-in-glass thermometer.
Multiple sensors continually monitor instrument function, displaying an error message if a problem is detected. The performance of the ionization sensor which detects the flash and fire points is continuously monitored, and the user is notified upon the need of replacement. If a flash is not detected 20°C above the expected flash point or at 420°C, then the flash point test is automatically aborted for safety.
This flash point testing system is easily interfaced with an external PC for operation and method updates. When performing a flash point test, the system will display the stirring speed, temperature curve, and current test status.
The system alerts the user if the first application of the ignitor results in a flash or if no flash point is detected at the end of the test program. If a flash is not detected 30°C above the expected flash point or at 400°C, then the test is automatically aborted for safety.
