Precisely controlled by GE's chilled mirror sensing technology - providing NIST traceable humidity,temperature and pressure measurement anywhere via the worldwide intranet. The Optica Chilled Mirror Hygrometer measures dew point temperature by regulating the temperature of a polished metal mirror by the use of optical feedback such that a constant mass of dew or frost is maintained. The temperature of the mirror is measured with a precise PRTD and is by definition equal to the dew or frost point.","keywords":"AMF, NCAS, Dewpoint, Hygrometer, Water, Relative Humidity, Moisture Content","identifier_set":["https://catalogue.ceda.ac.uk/api/v2/identifiers/517/?format=json","https://catalogue.ceda.ac.uk/api/v2/identifiers/518/?format=json","https://catalogue.ceda.ac.uk/api/v2/identifiers/12929/?format=json"],"instrumentType":"instrument","subInstrument":[],"responsiblepartyinfo_set":["https://catalogue.ceda.ac.uk/api/v2/rpis/2451/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/2452/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/49694/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/49693/?format=json"]}
