Humidity is measured in a wide variety of industrial applications. Each application has a different set of requirements for humidity instruments, such as measurement range, tolerance to extreme temperature and 
pressure conditions, ability to recover from condensation, and ability to operate in hazardous environments.
There is no single humidity instrument that is suitable for all needs. The document 'How to Choose the Right Instrument for Measuring Humidity and Dew Point' covers the following topics in order to help in selecting the right humidity instrument:
- Description of different humidity parameters
- Environmental conditions that influence the choice of humidity instrument
- Sensor properties that influence the choice of humidity instrument
- Practical guidelines for selecting a humidity instrument
