More than two years in development, the all-new HSG Labs Checker builds upon the success of Harkness’ previous device, the Digital Screen Checker, bringing to the cinema industry a state-of-the-art brightness and audio checking tool at an affordable price.

The all new HSG Labs Checker is a low-cost tool designed to help cinema owners, managers and staff monitor brightness levels and spot check audio systems in order to ensure presentation quality is maintained. It is also an ideal tool for home cinema installations.

Simple and easy to use, the Checker is a point and click device with an intuitive user interface designed for users with varying levels of technical expertise. The ergonomically designed hand-held device (which can also be tripod-mounted) allows users to quickly take measurements inside of a cinema to spot check various presentation parameters from industry reference measurement positions.

Brightness Measurement

Calibrated for use with all types of cinema projection including RGB laser illumination, the Checker’s 3° field of view, provides accurate brightness readings between 0 and 40fL with a tolerance of +/-1fL. The simplicity of the Checker lends itself perfectly to regular spot checking of brightness levels to monitor light degradation or during lamp installations using a white test pattern.

Audio Checking​

The HSG Labs Checker features two audio spot checking functions designed to help exhibitors to identify if audio levels have altered from known calibrated levels. Sound Pressure is displayed in dBC ensuring audio levels are suitable for cinema. The Checker also features a 10-band spectrum analyser enabling exhibitors to identify if an audio channel is defective.
