Inspectability scale & visual comparator UTE-3

The INSPECTABILITY SCALE is used under UV (black) light to determine if fluorescent brightness at the test surface is adequate and in proper contrast to ambient white light. It also can disclose whether the operator can see the size indication he is seeking.
The VISUAL COMPARATOR consists of sentences printed in Jaeger 1 and Jaeger 2 print sizes. The operator’s ability to read the appropriate sentence (J1 or J2 as required by the applicable specification) at the test surface, determines his visual ability under the test lightning conditions.
