Relative Humidity - Transmitters

GE Sensing's HygroTracT takes moisture monitoring to the next level with the launch of the Protimeter HygroTracT The HygroTracT is a wireless system for monitoring environmental conditions remotely in buildings. Small HygroTracT wireless sensors are installed throughout a building to monitor relative humidity, temperature and moisture content. Readings are transmitted to the data acquisition gateway that is connected to a dedicated and secure web server via Ethernet or phone line. Data can be viewed virtually live on the web site as well alarms set that send email warnings to your pc or mobile phone by way of text messages.
