From the manufacturer's datasheet for FTK+ active.
Overview
The FTK+ measures temperature and relative humidity in air ducts, ventilation plant and clean rooms, and calculates absolute humidity, enthalpy and dew point. The humidity accuracy is ±2% between 10 and 90% rH. The active versions have two analogue outputs for the chosen values. VV versions give 0 to 10 V or 0 to 5 V, selected by jumper. AA versions give 4 to 20 mA. The Relais versions add two floating relay outputs for a 2 point or 2 stage 2 point control. An LCD with a colour changing backlight and traffic light function is available on selected parts. A hinged cover, tool-free terminals and removable cable entries speed up installation. Settings can be made with the USEapp or uConfig. The probe has a stainless steel mesh filter, and a mounting flange is supplied.
