The Amphenol / Protimeter BLD9000 HygroTrac is a simple and cost-effective system for monitoring environmental conditions remotely in buildings. The Amphenol / Protimeter BLD-9000 HygroTrac Wireless Environmental Monitoring System measures and logs data parameters such as relative humidity, temperature and moisture in materials.

Small HygroTrac wireless sensors are placed in a building and readings are sent to the data acquisition gateway. The data acquisition gateway is connected to a dedicated and secure web server via Ethernet or phone line. The measurements can then be viewed from any internet connection using a secure password to access results.


Wireless Sensors
Transmit data at user-selected intervals to central data acquisition gateway up to 150 ft (46 m) away. Multiple sensors (up to 600 per gateway) can be installed all transmitting back to one or more data acquisition gateways. Frequency of reporting can be adjusted between 1 min to 24 hours.

  • HygroTrac Measures
    • Relative humidity
    • Air temperature
    • % moisture content in wood and %WME in other building materials.

Data Acquisition Gateway
Data collection point receives and stores data from all wireless measurement sensors. Information is then sent to a secure web server.

  • Data is sent via
    • Ethernet
    • Telephone land line (user dial out options: Use of dial up connections will require an ISP account.)
    • Up to 600 sensors can report to a gateway
