Rotronic Instrument Humidity and Temperature Measurement ...

1 15 HygroFlex3 seriesThe new HygroFlex3 series is the latest development in HVAC transmitters for relative Humidity , Temperature and dew point. Based on AirChip3000 technology, the transmitters offer high accuracy at a low new generation boasts a unique calibration and adjustment process as well as many other unbeatable innovations. At the same time we have taken the sensor technology to a whole new level of performance and reliability:The HygroFlex3 series offers you maximum reproducibility and a guaranteed system accuracy of < 2 %rh and K.

2 The transmitters come in various versions and there are also thermostats/hygrostats available for the duct and wall versions. Many useful functions can be activated with the optional HW4 applications in cost-sensitive applications, building management systems, museums, libraries, calibration and adjustment process Highest reproducibility Guaranteed system accuracy of <2 %rh and K Space, wall and duct mount versions Many useful functions can be accessed with optional HW4 softwareTRaNsmITTeRs8282822716 TRANsmITTeRsHF3x Space MountApplicationsHVAC applications, cost-sensitive installations, building management systems.
