Professional Videoinspection
The Wohler VIS 2000PRO is used for visual inspection of chimneys, ventilation lines, vents and pipes. The camera detects leakages and defects. Because of a pan and tiltable camera head, you can inspect every spot. 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, you can later upgrade your system, so it can also be used for other applications e.g. with a miniature camera head or a different camera rod.
You can carry all components directly in front of your body, so you don´t need a place to set the instrument onto.
