Description

The ALTA Wireless Duct Temperature Sensor uses an NTC type thermistor with UL listed plenum cable to accurately measure temperatures in duct work, while maintaining a sealed environment. Can be easily installed and mounted for long term use. * Actual range may vary depending on environment. ** Battery life is determined by sensor reporting frequency and other variables.
