A versatile gas transmission device with precise humidity control for QCM humidity sensor characterizations
Summary
An affordable gas delivery system for characterising QCM humidity sensors combines saturated salt solutions with gas mixing, switching humidity automatically in closed chambers shielded from outside air. Tested with a commercial hygrometer and a graphene oxide-coated QCM from 5 to 83% relative humidity, it repeated frequency shifts within 2% over ten hour-long cycles.
