Henke-Sass, Wolf endoscopes can be used up to a temperature of 120°C, although higher temperatures also occur sometimes. In such cases, a cooling mantle is the solution. Cooling mantles can be cooled either with air, nitrogen or water, and they enable endoscopes to be used at very high temperatures. The applications are very diverse, ranging from the inspection of a furnace or running turbine to observation of a flame. Just tell us what your application is, and we'll supply you with the solution.
