The Optidew High Performance Optical Dew-Point Transmitter works on the proven, fundamental optical dew-point measurement principle, giving unmatched and drift-free long-term performance. Optidew provides two linear 4-20 mA outputs in addition to serial communications, allowing set-up and monitoring by a suitable computer or PLC system or via specific Optidew logging software. An adjustable volt-free contact alarm means that Optidew can be used for direct process control.
