Humidity Measurement

What’s a hygrometer? It’s an instrument for relative humidity measurement. This means it detects the moisture content in the atmosphere. Humidity measurement is often combined with temperature measurement in a single digital hygrometer that’s useful in industrial spaces, outdoor environments and HVAC procedures. Digital hygrometer readings can be obtained through the use of resistive and capacitive sensors whose electrical resistance is impacted by moisture.

A humidity recorder is an instrument for monitoring and recording humidity measurements, with models available to monitor both temperature and humidity. The traditional chart recorders report data over time on paper. Pen movement is generated by an input signal, and graphs or charts are created. When a digital recorder is used, humidity data will be recorded digitally for download.
