Digital Screen Verifier

By Harkness Screens Ltd

This app is only available on the App Store for iOS devices.


Designed solely for measuring brightness levels from cinema screens using a white test pattern the Digital Screen Verifier from Harkness Screens is a quick and easy to use tool designed for cinema engineers.

Utilising ground-breaking proprietary technology, the Digital Screen Verifier from Harkness Screens is a unique utility that allows cinema engineers and exhibitors to ensure that brightness levels in digital cinema are regularly checked and maintained. Quick and easy to use, this relatively accurate low-cost light measurement tool allows brightness readings to be taken (in foot lamberts) using white test patterns from a digital cinema projector. Its unique functionality allows light readings taken in the field to be directly imported into Harkness’ cloud-based Digital Screen Archiver tool in real-time to form a semi-automated entry-level solution for screen monitoring and auditorium maintenance.

The Digital Screen Verifier has been rigorously tested to confirm its accuracy. The tool is calibrated to measure light between 0 – 30fL with a high degree of accuracy however accurate readings are dependent on a number of variables including the cleanliness of the camera lens and the measurement position in the auditorium.

Whilst the results displayed in the Verifier should be within the set tolerance of other measuring devices such as spectroradiometers there are any number of variables which could alter the outcome significantly. Harkness Screens always recommends users consult with Harkness before applying the information supplied in the Digital Screen Verifier in to real-world projects.

What's New in Version 2.0

New mode added for taking 5-point light readings.

Customer Reviews

Not accurate at all - save your money!

This app reads 13fl hotter than our Konica-Minolta CS-200 calibrated meter! For the cost of this app, I didn't expect much but I would think it should be a bit more accurate, Harkness.
