Product details

Optidew high-performance optical dew point transmitter is based on the most basic optical dew point measurement principle, and has excellent performance and long-term stability with zero drift. Its measurement range is wide, usually covering 0-100% RH at temperature.

Optidew provides two sets of linear 4-20 mA outputs and a serial port communication, which can be remotely controlled and observed through a matching computer or PLC system or dedicated Optidew data acquisition software. An adjustable voltage release contact alarm allows the product to participate in direct process control. You can also choose to order a local display module to indicate the measured humidity value.
