The SP20 is one of the last manual methods that has never been automated before. Performing the smoke point test manually requires highly skilled technicians with years of experience. Additionally, the manual test is time consuming. The current visual rating method used for specification purposes suffers from the drawback of operator subjectivity. The visual measurement of an open flame is a challenging exercise and dangerous for lab personnel. The visual rating of the flame varies from one operator to another.

The SP20 Revolutionizes Smoke Point Testing, it uses a system that adjusts the size of the flame associated to a video camera that observes the flame. When the flame attains the shape described in the test method, the SP 20 memorizes and reports the height of the flame. Every test is fully documented and traceable which is important for aviation industry quality procedures.

The SP20 comes with embedded temperature, humidity and pressure sensors. An atmospheric conditions compensation (patent pending*) can then be applied. Upon switching on, the SP20 is ready for a direct sample measurement, no matter of the ambient conditions, reducing by 2 hours the labor normally spent for the complete calibration procedure, including the preparation of the 7 mixes.
