Humidity Temperature and Dew point Transmitters

The ROTRONIC humidity, temperature, dew point transmitters and probes feature reliable, accurate measurement and the ability to calibrate on-site. Designed for fixed installation, these precision instruments are used for humidity, temperature or dew point measurement in applications ranging from the control of a simple office building to specialized applications such as a computer room, clean room, pharmaceutical research room, stabilization room or storage area, semi-conductor fabrication area, or the control of a manufacturing process.
