PRODUCT DESCRIPTION
The TH-MSZ is a hair hygrograph — a mechanical humidity recorder whose human-hair sensing element drives a pen across a daily or weekly chart. It records 30–100%RH continuously with no electrical power, producing a permanent paper humidity record.
Hair hygrographs remain a reference instrument in meteorological practice because the sensing principle is direct, stable and fully independent of electronics.
