Performing the smoke point test manually requires highly skilled technician with years of experience. Additionally, the manual test is time consuming. The automation of the smoke point test introduced by AD Systems had drastically improved the precision of the test in comparison with the original manual method, and consequently became the referee in ASTM D1322 and IP 598.
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 SP20 memorizes and reports the height of the flame.
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.
