Humidity Sensor & Instrument Calibration Services
Thermocouple Calibration, Hygrometer, Pyrometer, and More Moisture Calibration For humidity-reading instruments to function consistently and within accuracy requirements for an acceptable period, humidity calibration is required. In many processes and manufacturing settings, humidity is an important environmental component. Thus, it is essential for quality control to maintain trustworthy devices for the precise measurement of relative humidity.

Overview
Humidity calibration is the verification and adjustment of humidity-measuring instruments, such as hygrometers, humidity sensors, dataloggers, and climate chambers, against reference standards. The purpose of this calibration is to ensure the accuracy and reliability of the humidity measurement data. The calibration of humidity measurement instruments establishes the relationship between the output of the device and the actual relative humidity (%RH) or dew point temperature, along with the associated measurement uncertainty. This is based on the ISO/IEC 17025 and EURAMET guidelines.
Accurate humidity measurement is important in the pharmaceutical, food, electronics, and HVAC industries because uncontrolled humidity can cause process failures.
Scope, Applications, and Benefits
Scope

Frequently Asked Questions
Humidity calibration is the process of verifying and adjusting humidity measuring devices to ensure their readings are accurate and consistent with traceable reference standards under controlled environmental conditions.
It ensures accurate humidity readings, which are critical for maintaining product quality, preventing material degradation, and complying with industry standards in sensitive environments like laboratories and manufacturing facilities.
Relative humidity is the percentage of moisture present in the air compared to the maximum amount the air can hold at a given temperature.
Temperature fluctuations, sensor aging, contamination, and improper handling can affect measurement accuracy.
Calibration is typically performed annually or more frequently depending on usage, criticality, and regulatory requirements of the application.
