Description
The SE - DEW - 100 Dewpoint Transmitter makes monitoring dewpoints as easy as measuring temperature or pressure, and can be instantly incorporated into air or gas measurement and control systems. We highly automated manufacturing, calibration and test processes make the SE - DEW - 100 not only a very rugged and reliable instrument but also very competitive in price. By taking advantage of sensor program, users can be assured that their process moisture measurement facility is never interrupted. It is very easy to install and maintain and comes with a full world-wide backup and service program.
