High Frequency Nondestructive Testing Equipment / LED Film Viewer Size 360×430mm

High Frequency LED Film Viewer Window size 360×430mm 70000- 118000cd/m2

The excellent selected material

the viewer’s viewing screen and optical path material are all adopted of Acrylic glass plate manufactured by Japan Mitsubishi Liyan Co. Beyond the glass has a light transmittance and durability to ensure the non-deformation, do not change color.

Using the latest technology abroad

It adopts the newest backlighting technology of color LED

Standards conforming: GB/T4730-2005, GB/T7903-1999

1.The Conformation of the Whole Machine

2.The Technical Parameters and Specification

2.1 Optical Parameters

1) The viewing screen surface is no glint phenomenon, the screen central lightness ＞7000cd/m²

2) The viewing screen light dispersion coefficient ＞0.6

3) The viewing screen each part lighting’s equality coefficient ＞0.7.

2.2 The continual working time ＞24h

2.3 The viewer can be lightened within 10s, the lightness stable time ＜5 minutes

2.4 The viewer working noise ＜40dB

2.5 After working 1h, the viewer box frontal surface temperature ＜60℃

2.6 The high frequency voltage stabilizer’s working frequency is 30kHz~100kHz

3. Installation

To put the industry film viewer on the desk directly.

4. The Starting Process

4.1 To put the power adaptor’s AC plug connected into the AC socket on the viewer right side

4.2 Again to put the voltage stabilizer another 220V three-pin-plug connected into the 220V/50Hz power socket

4.3 To turn on the power switch under the panel of the viewer, the viewer immediately lightened, within 15 minutes it reaches normal lightness.

5. Notices

5.1 It must use the original power adaptor, the electric plug must has a good eathing, otherwise it easily causes malfunction. If using other power adaptor it would make product damage. If the product is too hot, please to unplug the power adaptor.

5.2 The product warrant period is one year, please do not self-open for repairing, otherwise it would cause damage.

5.3 Please do not use the product in humid place (such as bathroom), otherwise easily suffering electric shock.

5.4 Please do not use the product outdoor and the place easily meeting thunder, otherwise it easily suffering electric shock.

5.5 Please do not use the product near fire, nor do impact or throw.

5.6 Please do not use alcohol-like organic solvent to wipe the surface of film watching screen, you may use soft wet cloth to wipe, then again use dry clean soft cloth to wipe.

5.7 Under turning on state, if unplugging voltage stabilizer, the film-watching screen would have residual light, that is not belong to malfunction.

5.8 Not using for a long time, please unplug power and voltage stabilizer.
