Transparency Tester For Blown Bottles

Transparency tester is a very important testing instrument in industries dealing with plastic like bottle manufacturing units. Transparency of bottle becomes crucial. Depending upon the requirement of the industry and properties of the packed product, the transparency is pre-decided. To achieve the high level of consistency and uniformity, the transparency testers are used.

The transparency tester for Blown bottles is used for testing the transmittance of light through a completely blown bottle which this helps in assuring the best quality of the Bottles with the desired level of transparency. The optical series principle diagram of integration ball type light transmittance is used for the device. The operation of the instrument is done by installing the white standard plate to the instrument. After that, the current reading of the device’s meter (T1) is adjusted to 100 z. Once the reading is adjusted, the amount of incident light is controlled below the level at which the white standard plate is installed.  Now the evaluation of the current reading of the meter (T2) is performed. The light transmittance of through the test sample is calculated by the given formula.

T= T1/T2 x 100,

where T is the total transmittance of light through the test sample.
