Transparency Tester

Test specimen shall be prepared from the part of container where markings are not found. The optical series principle diagram of intergration ball type light transmittance measurement device. The size of test specimen shall be 50mm X 50mm and the thickness shall be the original thickness of the test specimen. The test specimen shall be prepared.

We install the white standard plate, adjust the reading (T1) of the device’s current meter to be 100z: adjust the amount of incident light Under the status where the white standard plate is installed, install and measure the test specimen to obtain the indication (T2) of the current meter- The full light transmittance shall be calculated according to the following formula.

T = T1 * T2 / 100

T = full light transmittance, percent
