FA 550 - Dew Point Sensor in a Sturdy Aluminum Housing 

FA 550 - Dew Point Sensor in a Sturdy Aluminum Housing 

Robust dew point sensor for compressed air and gases.

The FA 550 is ideal for dew point measurement in outdoor environments and reliably determines dew points even in harsh industrial conditions.

Application examples: 

• Dew point measurement in compressed air systems after adsorption dryers, membrane dryers, or refrigeration dryers. 
• Measurement of residual humidity and dew point in gases such as oxygen, nitrogen, argon, hydrogen, natural gas, biogas...
