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.

Additional Guidance
The Digital Screen Verifier has been rigorously tested to confirm its accuracy.  The tool however is 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 Digital Screen 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.
