Cost-effective mobile device for brightness and audio checking for audio video projection system.
The HSG Labs Checker is a brightness and audio checking device for Cinema Owners, Technical Teams, Managers and Staff. Simple and easy to use, the HSG Labs Checker is a point and click device with an intuitive user interface designed for users with varying levels of technical expertise.
Capable of measuring brightness levels from 0 to 40 foot lamberts (fL), the Checker offers real-time feedback that supports tasks like new lamp installations, routine maintenance, and compliance checks.
It’s equally effective in 2D and 3D projection environments, including the ability to take measurements through 3D eyewear. The unit itself is battery powered and features a clear LED digital display that shows readings to at least one decimal point.
Made in Europe
Key Functionality
- Measure screen brightness (with a range of 0fL to 30fL)
- Ensure screen consistency throughout the cinema (accuracy to 1 fL)
- Measure instant accurate readings for both 2D and 3D (through the eye wear) screens
- Easy to use with simple optical screen alignment viewers, mounting tripod and 3D lens holder
