Elcometer Inc.: Elcometer 320 is a powerful system that can simultaneously monitor climate parameters in up to 254 distinct locations. It is launched along with the ElcoMonitor™ software, allowing for failsafe, real-time climate observation. Audible and visual indicators provided by a signal tower give an instant warning that climatic conditions have surpassed parameters. The system provides an accurate indication of relative humidity, air and surface temperature, specific humidity, and the difference between relative humidity and dewpoint.
