Educational Recording and Broadcasting System CNAS Testing Report:

If you encounter a situation during the bidding process where you are required to provide a third-party optical test report for an all-in-one recording and broadcasting machine, and the report must include CNAS or CMA markings, and you're unsure where to apply for it, you've come to the right place. We have extensive experience in handling bidding reports and numerous case studies of testing projects. The following content of testing projects is for reference only:

1. Integrated modular design with a metal body, featuring concealed wiring for internal functional modules, ensuring no exposed wires on the exterior. The corners are ergonomically rounded to prevent bumps, with smooth surfaces free of sharp edges, burrs, or scratches on the front interface edges.

2. The product's thickness is 54mm, with the central area of the main board featuring an ultra-high-definition LED LCD display screen. It supports both human-machine interaction touch operation and the display of videos, teaching materials, and other content. The side panel is a writing board, and the seam between the main board and the side panel is only 0.3mm wide.

3. Features an integrated pen holder design for easy cleaning of dust in the pen slot, and provides space for chalk, page turners, infrared pens, smart pens, and other teaching supplies.

4. The writing boards on both sides are made of organic composite materials, featuring a smooth, wear-resistant, and shockproof surface. They support various writing tools such as dust-free chalk, regular chalk, and eco-friendly water-based pens. The content written on the side panels can be independently saved on both sides or dragged into whiteboard software for storage in image and video formats. The recording program runs silently in the background. The side panels are made of magnetic material, capable of吸附 displaying teaching materials such as courseware and exams.

5. The writing surface has passed the wear resistance test, with the haziness caused by abrasion being less than 1%.

6. LCD screen supports 4096x2160, 3840x2160、2560Multiple display resolutions, including 1440.

7. Features an A+ grade LCD screen with a contrast ratio of 6000:1, brightness of 500 cd/㎡, a viewing angle of 178°, response time below 8ms, and color depth of 1.07B; refresh rate supports adjustable range from 60Hz to 144Hz.

8. The screen surface is made of anti-glare tempered glass, featuring scratch and impact resistance. It measures 3mm in thickness, with a light transmittance of 94% (±2%), a haze of 8%, and can display clearly in a 400K LUX bright light environment.

9. To prevent wear and tear over long-term use, the screen surface is made of tempered glass with a hardness of not less than Mohs 8H (hardness greater than graphite 9H), color gamut of NTSC 100%, and 130% under the Rec.709 standard color gamut format. The screen surface has a haze of ≤1% due to abrasion.
