Modular system
|
The Wohler VIS 400 visual inspection system is designed for top down chimney inspection, and vertical inspection of vents and flues.
Modular by design, it is possible to combine the Wohler VIS 400 Visual Inspection System with a variety of camera vipers, camera cable and camera heads. For instance, simply connect either the Wohler 2" diameter or the 1.5" diameter pan & tilt camera head to carry out a variety of inspections. Both of these cameras pan 360 and tilt 180 while offering the best possible lighting. After panning and tilting, the home function automatically aligns the angle of the 1.5" diameter color camera to straight ahead with a simple push of a button.
View, speak and save
The Wohler VIS 400 will make a video recording of the inspected line run. When damage is discovered, begin the voice recording function to annotate the recording. As well as recording video, you may also take and save still photos at the press of a button.
Knowing where really matters
To be able to assess and specifically target repair work, we at Wohler have perfected the technique of precisely locating the camera head. The distance and the position of the head are displayed on the monitor. The top and bottom of the pipe are displayed on the monitor at all times, even if the camera is being guided up or down or if it is moving left or right. It is even possible to locate the 1.5" diameter color camera head wirelessly - utilizing the new Wohler L 200 Locator.
