From the manufacturer's datasheet for FTK+ RS485 Modbus.
Overview
The FTK+ measures relative humidity and temperature in air ducts and clean rooms. It can also calculate absolute humidity, enthalpy and dew point. Humidity accuracy is 2%. It connects over RS485 Modbus RTU and has two analogue outputs of 0 to 10 V or 0 to 5 V. The probe is a black PA6 tube of Ø19.5 mm with a stainless steel mesh filter, in three lengths. A colour LCD with traffic light function is available on the LCD versions.
