To this end, the present invention provides a measurement method of distinguishing dew and frost point using a quartz crystal microbalance dew-point sensor in low temperature, comprising the steps of: measuring a resonant frequency of a quartz crystal microbalance dew-point sensor while slowly dropping temperature; observing shock waves of the resonant frequency; and determining dew point or frost point through the observation of the resonant frequency and shock waves of the quartz crystal microbalance dew-point sensor."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Measurement method of distinguishing dew and frost point using quartz crystal microbalance dew-point sensor in low temperature","description":"The present invention relates to a measurement method of dew-point in low temperature, and more specifically to a measurement method of accurately distinguishing dew-point and frost-point using a quar","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8485720","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
