Écran 55" durci

Following the success of the roda HEL concept at home and abroad, this product family is complemented by the HEL (High Resolution Electronic Positioning and Display) RD55.
HEL RD55 is the compact version that is used as a position table or also as a position display. 
The 4K resolution and 55“ display diagonal make the HEL RD55 ideal for working with 3D terrain models or for image evaluation.
The HEL RD55 is operated either by 10-finger touch or by mouse.
The 10-finger touch system used here is based on LED technology, which allows unrestricted operation even with gloves and when the display surface is wet. At the same time, the use of LED touch technology also enables approval according to SDIP Level B (ER). 
The design of the HEL RD55 allows it to be used even in harsh environmental conditions, IP65 on the front, IP54 on the back, temperature range from -20 °C to +55 °C.  The transport takes place in a specially adapted TuLB.
