I. Purpose And Scope Of Application

The sample burns in the standard lamp, and the change of flame height is reflected on the background of MM scale. The measurement results have high repeatability. The whole instrument has compact and complete structure and no circuit components, which conforms to GB / t382 and astmd1322.

II. Functional Features

1. Kerosene smoke point tester adopts millimeter scale background, which can read data clearly

2. The whole instrument is compact and complete

3. Kerosene smoke point tester adopts plug-in structure, which makes it more convenient to replace the wick

4. Kerosene smoke point tester adopts special glass observation window, which is easy to operate

5. The kerosene smoke point tester is easy to operate and has high repeatability
