Screen Brightness/Luminance Meter (SM208)
The SM208 screen luminance meter is specifically engineered for measuring luminance across various display technologies including fluorescent screens, CRT displays, monochrome transmission screens, color transmission screens, monochrome backlit LCD screens, LCD backlights, mobile color LCD screens, color computer TV screens, and security indicating screens. This versatile instrument also serves applications in medical X-ray, electroluminescence, and other specialized measurement fields.
Key Features
- Silicon photocell detector with excellent stability, light resistance, and impact resistance for accurate luminance measurement with rigorous visual correction
- Wide measurement range from 0.01 cd/m² to 39,990 cd/m² without requiring a dimmer
- Digital display with superior reproducibility, featuring data retention and peak hold functionality
- Low power consumption - 9V laminated battery provides up to 100 hours of continuous operation
- Compact metering probe with 20mm diameter - requires measured screen diameter greater than 20mm with tilt angle under 5 degrees
- Portable design for easy handling and operation
