The Dickson Difference: Why Quality Humidity Sensors Matter
Don’t let humidity lead to product loss or compromise your compliance records. Dickson humidity sensors and probes are your first line of defense, providing accurate readings to keep moisture-sensitive items safe and keep your operation compliant. When paired with Dickson data loggers and OCEAView™ software, our probes and sensors offer a complete 24/7 monitoring system that sends alert notifications when there is a notable excursion so you can promptly take action.
Sensor Calibration Meeting the Highest Industry Standards
Calibration services from Dickson provide you with the added peace of mind that your humidity sensors are consistently operating with exceptional accuracy.
- Decades of experience in temperature and humidity mapping, sensor installation and validation
- ISO 17025 accredited by the Comité Français d’Accréditation (COFRAC)
- Engineers and metrology professionals with years of calibration expertise
Calibrating your humidity sensors at least once a year is best practice, however the precise frequency varies greatly depending on its application. Learn more about Dickson’s calibration services and get guidance on your specific application from our experts.

4 Keys to Choosing Humidity Sensors for Your Application
- Find the Correct Sensor Type: There are three basic types of humidity sensors:
Capacitive sensors measure relative humidity and are known for high accuracy over a wide range.
Resistive sensors measure relative humidity and are less accurate than capacitive sensors. They are often used in applications where cost is an overriding concern.
Thermal conductivity sensors measure absolute humidity and are used when precise moisture control is critical.
- Select for Accuracy: Look for sensors or hygrometers with high accuracy and a low margin of error. Accuracy in humidity sensors is typically expressed as a percentage of the reading, plus or minus a certain value.
For example, a sensor with an accuracy of ±2% RH means that the measured reading could be off by 2% above or below the actual humidity level. A ±2% RH is generally considered highly accurate and suitable for applications in pharmaceutical manufacturing and storage, calibration laboratories, food processing and storage and semiconductor manufacturing.
- Pay Attention to Response Time: The response time of the sensor refers to how quickly it reacts to changes in humidity levels. The average response time for humidity sensors is between 5-30 seconds.
Faster response times are essential in applications where rapid changes need to be detected and addressed promptly. Consider the required response time for your application and choose a sensor that meets those requirements.
- Consider Environmental Factors: The environment in which the sensor will be used can affect its performance and lifespan. Consider factors such as temperature, pressure and the presence of contaminants or corrosive elements. Choose a humidity sensor that is designed to withstand the specific environmental conditions of your application.
