●This state-of-the-art solid-state sensor plugs into its wall-mounted receptacle for on-site,
   continuous monitoring of relative humidity and temperature in critical or controlled
   environments.
●Two separate 4-20 mA analog signals which can be powered by a single external voltage
   source can be sent to remote panel meters, controllers, or data acquisition systems.
●Applications include environmental chambers, HVAC installations, building management,
   clean rooms, calibration labs and museums. The HI 8666 has an accuracy of ±2% RH and
   ±1%ºC.
●It can be used in dusty environments by adding a furnished removable sintered-metal cap.
●With its plug-in convenience, the unit can be quickly removed and replaced; so the cleaning
   or calibration checks cause no costly downtime in the production area.
