Part numbers
From the manufacturer's datasheet for FTK+ RS485 BACnet.
Overview
The FTK+ measures relative humidity and temperature in air ducts and clean rooms, and can calculate absolute humidity, enthalpy and dew point. The humidity accuracy is 2%. Air speed at the probe must not exceed 12 m/s. It outputs over RS485 BACnet MS/TP and as two 0 to 10 V or 0 to 5 V analogue signals. The probe comes in 140, 270 and 400 mm lengths, each with or without a colour-changing LCD. A mounting flange is supplied.
