Labtron Open Cup Flash Point Tester features adjustable heating power for precise control over temperature settings, with an electric current meter to display power consumption. These include menu prompts and guided input functions, simplifying the setup process for users. Their electric ignition mode ensures a reliable start-up for smooth operation. They have a detachable ionization ring for easy cleaning, maintenance, and longevity. Our open cup flash point tester has a barometric correction for temperature calibration, ensuring accurate readings and accounting for atmospheric pressure variations.




The Automatic Cleveland Open Cup Flash Point Tester LOFP-A12 uses a small open flame for ignition, which is compatible with liquefied petroleum gas (LPG), butane, natural gas, or pipeline gas. The gas should be clean, dry, and regulated at a pressure below 10?kPa to ensure proper flame generation. Using contaminated or unregulated gas can result in ignition failure or unstable flame size. We recommend performing gas line checks and leak tests before each use.
Our Automatic Cleveland Open Cup Flash Point Tester LOFP-A12 may produce unreliable or abnormally low flash point readings if the sample contains water, dust, or volatile impurities. These contaminants can lead to premature ignition, posing safety hazards and resulting in invalid data. We recommend that all samples be clean, homogenous, and prepared according to standards like ASTM or ISO. Contaminated samples can also cause buildup or damage to the test cup and flame sensor.
Labtron advises that the Automatic Cleveland Open Cup Flash Point Tester LOFP-A12 be operated only in well-ventilated areas, far from any external ignition sources or flammable materials. Users should wear gloves and safety goggles when handling petroleum-based samples. Before testing, check all gas line connections for leaks and ensure the flame ignition area is clear. The tester should never be left unattended during a test, and users must follow emergency shutdown procedures in case of flame failure or system fault.
The Automatic Cleveland Open Cup Flash Point Tester LOFP-A12 commonly encounters user errors such as overfilling the sample cup, improper sample mixing, incorrect flame size, and failure to input or verify atmospheric pressure. These mistakes can lead to inaccurate or inconsistent flash point results, compromising test reliability. We advise users to follow the standard operating procedure (SOP) closely, conduct thorough pre-test equipment checks, and pay attention to system prompts and alerts. Regular training sessions and periodic refresher programs are also recommended to minimize operator-related errors.
Labtron Automatic Cleveland Open Cup Flash Point Tester LOFP-A12 may display an error code or flame failure warning if there is an issue during testing. In such cases, users should first pause the test and allow the unit to cool down safely. We recommend checking the ignition system, confirming a stable gas supply, and removing any blockages or residue from the flame nozzle area. Refer to the error code guide in the user manual to troubleshoot accurately. If the issue continues, the test should be restarted with a fresh sample, and users should contact our technical support for further assistance.
