Wöhler VIS400 Inspection System

The Woehler VIS400 Inspection System is ideally suited to visual inspections on ventilation / air conditioning ducts, chimneys, chambers and flue gas systems along with search and rescue operations into vertical chambers such as mine shafts and wells. The coloured image, bright lighting and the rotatable lens system provides easy handling and precise feedback of the viewed area.

Because of a pan and tiltable camera head, inspections of difficult to reach areas can be acheived with ease. The results of the inspection can be recorded to a CF- memory card in the instrument either as pictures or videos. Because of the modular design, the system can be upgraded at any time for use in aother applications with options such as with miniature camera heads or different length / diameter camera rods.
