We are offering temperature humidity transmitter. rht - 1000 humidity and temperature transmitter convert the humidity and temperature measured by two sensors into a 4÷20 ma signal. the accurate design and choice of components make the instruments precise and reliable for a long working life. The instruments have two sensors, a capacitive sensor for measuring relative humidity and a platinum resistive sensor for measuring temperature. detail information : •rh humidity and temperature •fast , stable and accurate. •ip 65 enclosure. •zero and span •loop powered 4- 20ma o/p specifications : measuring range : humidity : 0-100 % rh. temp : 0 - 80 c. optional temp range : -20 - 80 c / 0 - 50 c accuracy @ 25ºc : 2 % rh , ± 0. 3º c temp.
