From the manufacturer's datasheet for FTK+ Basic RS485 Modbus.
Overview
The FTK+ Basic measures temperature and relative humidity in air ducts, ventilation plant and clean rooms, and calculates absolute humidity, enthalpy and dew point from them. The humidity accuracy is ±2% between 10 and 90% rH. Values are read over RS485 Modbus RTU, with the address and bus settings made on DIP switches. The probe has a stainless steel mesh filter and is available in three lengths. A hinged cover, tool-free terminals and a removable M20 cable entry speed up installation, and a mounting flange is supplied.
