OEM Wireless Water Temperature SensorThe OEM wireless water temperature sensor uses a thermistor to accurately measure temperatures from -40°C to +125°C. Perfect for water or non-combustible liquid storage tank temperature monitoring. All sensor data is securely transmitted through an OEM wireless gateway to the iMonnit Online Sensor Monitoring software where it is stored and viewable from any web enabled device. The iMonnit online software system is completely white label (private brand) capable, allowing you to offer the online monitoring service as your own. Email and SMS text messages can be configured through the online system to alert users immediately when a defined parameter has been met or exceeded. « Learn more about OEM online monitoring software Product Features:

* Battery life depends on sensor reporting frequency and other variables.
** Hardware can not withstand negative voltage. Please take care when connecting power.
*** At temperatures above 100°C, programmed memory in electronics can be lost.
**** 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.
