Humidity Temperature and Dew point Transmitters

The ROTRONIC humidity, temperature and dew point transmitters and probes feature reliable, accurate humidity, temperature and dew point measurement and the ability to calibrate on-site. These precision instruments can be used to control humidity, temperature and dew point in applications ranging from the measurement of ambient conditions to the measurement of industrial processes.
