Additional Information

* Actual range may vary depending on environment

** Battery life is determined by sensor reporting frequency and other variables

*** Hardware cannot withstand negative voltage. Please take care when connecting a power device. 

**** While the wire leads and thermistor have a water tight seal, the electronics housing (RF portion) is not sealed for wet environments or outdoor use. If needed, we recommend using Monnit industrial water temperature sensors.
