Smoke testing equipment was development based on national standards GB/T20795-2006, professional for the determination of vegetable oils smoke point. Its use is as follows:

Features: As long as the value of the hypothetical oil smoke point directly set when the instrument is warming settings 42℃, the instrument automatically enter the control. Then per-minute 5-6℃ rate of warming. Smoke to observe and record.

Operation: open the instrument the right side of the power switch is the number of lights, press the SET key, the upper temperature number "50" the words, the lower part of the small number appear to beat. Press the shift key. Small significant number of would-by-turn transform the beating. Press the "+" - "button can be set to a significant number of each in turn beat, is set up. Then set the key, small significant number of stops beating, appeared to set a good value, and the settings are recognized. Significant number of windows show the temperature value. As the temperature rises, the displayed number followed by the change, and apparatus for automatically tracking and control. When close to the value set by 42℃, the instrument automatically transferred to the heating control rate of 5-6℃ per minute.

This warming regional careful observation of the smoke smoke, when the sample a small amount of smoke, while continuing to have a light blue smoke coming out, with spotlights lighting the temperature reading to see smoke, quickly press the lock button. The number of temperature significantly locked. Is the smoke point temperature of the sample. Sometimes samples of continuous smoke, emit some faint smoke, but no effect on the determination results. When mistaken observation, and then lock the key referral lock, the instruments continue to heat until the clear smoke judgment points, and then lock key, the significant number will be locked again. If a significant number over a set value, the sample did not smoke, and the instructions assume that the value is incorrect, then no need to change, continue to observe until a smoke and then lock. Two-sample allows the error does not exceed 2℃, find the Mean is the test results.
