Compressed air is used for controlling break systems and door openers of rail vehicles. This compressed air has to be free from any condensate otherwise the brake system and the pneumatic door openers may freeze in winter and there could be corrosion damages in the distribution network and at pneumatic components (cylinders, valves). For this reason a regular dew point measurement is essential.

Especially for dew point measurement in compressed air systems of rail vehicles CS Instruments GmbH has developed the portable dew point meter DP 300 for increasing the operating safety.
