Dry Bulb ThermohygroMeter

The dry bulb hygrometer measures ambient temperature and humidity through mechanical or electronic sensors. Temperature detection relies on the deformation of bimetallic strips or thermistors, while humidity detection utilizes changes in the length of hygroscopic materials such as hair or nylon, or variations in capacitance values. It is used for environmental monitoring in places such as laboratories and warehouses, providing data references in processes like paint drying and paper storage.
Selection
When selecting, ensure the measurement range covers the extreme values of the usage environment. Temperature is often chosen within -10℃ to 50℃, and humidity within 0% to 100% RH. Accuracy should be determined based on requirements; for general applications, ±1℃/±5% RH is sufficient. Mechanical types require regular calibration, while electronic types require attention to power supply and sensor lifespan. For outdoor use, consider the protection rating and ensure the interface type matches the recording equipment.
