What is a common error when using an electronic hygrometer?

Failure to acclimate the instrument to the environment is a common error when using an electronic hygrometer because these devices are designed to measure humidity levels accurately based on the ambient conditions around them. When a hygrometer is moved from one environment to another, it may take time for the instrument's sensors to reach temperature and humidity equilibrium with that new environment. Without proper acclimation, the readings may be inaccurate and do not truly reflect the actual conditions.

This consideration is important for achieving reliable measurements, especially in applications sensitive to humidity levels, such as coatings, where moisture content can significantly affect adhesion, cure times, and overall performance. Thus, taking the necessary time to allow the hygrometer to adjust is essential for ensuring accuracy and consistency in readings.
