Description

The Monnit 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.



Features

  • Probe temperature range of -40°C to +150°C ( -40°F to +302°F )
  • Accurate to +/- 1° C (+/- 1.8°F)
  • User Calibrated Accuracy +/- 0.25° C (±0.45°F @ 77°F)
  • UL listed plenum probe cable

  * Actual range may vary depending on environment.
** Battery life is determined by sensor reporting frequency and other variables.
