Identify the sample
Use the sample label visible beside the instrument. A reading without a sample identity cannot support a product claim.
Sample measurement evidence
Window film quality records with visible evidence boundaries.
This page shows two sample readings visible in Linshang LS182 instrument photos. The values belong to the identified samples only; they are not third-party certifications or guarantees for every product and batch.

How to read this page
Evidence first, then the correct scope of the claim.
Record the display
Keep the original image showing the instrument model and all displayed values instead of copying one headline number.
Limit the conclusion
Treat the image as a sample snapshot. Batch consistency, calibration and test-standard claims require additional records.
Instrument-photo records
Two identified sample readings currently supported by source images.
The values below are transcribed from the visible meter displays. The source images do not provide a test date, operator, batch number, instrument serial number or calibration record.
The meter model is visible in both source photos.
The readings are photo snapshots, not laboratory certificates.
The values are not stated as universal specifications for all film.
These fields must be added before a controlled test report can be issued.
Next record standard
What a stronger repeatable measurement record should include.
These are the fields LogicFilms intends to request and retain for future controlled records; they are not claims that every existing test already includes them.
Traceability
Product series, shade, internal code, roll or batch number, test date, location and operator.
Instrument record
Brand, model, serial number, latest calibration date, settings and the original uncropped display photos.
Repeat readings
Multiple readings at the same sample position, with every result retained and the scope limited to the tested sample.
