The ALTA Industrial 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.
