DeltaOhm HD 2301.0

DeltaOhm HD2301.0 je prijenosni uređaji za merenje relativne vlage i temperature pomoću Pt100 ili termopara, kombinirane sonde za vlagu i temperaturu. Uređaj je opremljenim velikim LCD zaslonom.
Sama temperatura se mjeri uranjanjem, penetracijom, kontaktom i nastrujavanjem (zračna sonda). osjetnici koji se koriste su Pt100 i Pt1000.
Kada je spojena sonda za vlagu/temperaturu uređaj kalkulira i prikazuje apsolutnu vlagu, točku rosišta, djelomični tlak pare, temperaturu mokrog termometra (WBT), omjer miješanja, entalpiju i indekse ugode. Sonda se automatski detektira i dolazi kalibrirana (podaci su spremljeni u samoj sondi)
