The smoke alarm test tunnels are suitable for controlling the quality of optical detectors, ionization detectors and heat detectors. Our test tunnels are constructed of stainless steel sheet, are double walled and heat insulated. The inner lining has a cross section of 0.4 x 0.4 m and the outer lining is 0.5 x 0.5 m. The overall length of the channel is approximately 4.20 m, the channel (without frame) is 2.10 m high.
 
Features
 The tunnels are modular and are assembled from replaceable channel segments and elbows. It is thus possible to extend every channel at a later date, e.g. by adding a cooling segment with a pneumatic telescopic refrigeration system.
 
Accessories
 · Thermometer, anemometer and extinction measuring device .
· An aerosol generator with process control computer that regulates the wind speed and temperature in the channel, generates the required concentration and temperature ramps and automatically cleans and cools the channel after each measurement.
· An ionisation measuring instrument (MIC) is not installed as standard. However, the corresponding clamp for installing an MIC is fitted.
