Wireless Temperature Sensor with 3 ft External Probe

The wireless temperature sensor uses an external sensor probe to measure temperature with more accuracy and greater thermal range. Perfect for fast changing, temperature critical applications such as coolers or heaters. User customization allows you to set the frequency of readings and the ability to set thresholds for "Alarms", "Alerts" and "FYIs"

Monnit WIT Wireless Sensor Specifications
  • 900, 868 and 433MHz operating frequencies
  • 250 - 300 ft. non-line-of-sight device range*
  • Replaceable 3.0V battery
  • At 1 hour heartbeat setting, coin
    cell battery will last ~ 1-2 Years. **
     
  • Accurate to +/- 1°C (1.8°F).
  • Operating temperature range: -40°C to +125°C.
  • Good for fast changing temperature.
  • 3 ft external temperature probe.
  • Small size is ideal for embedded applications.
  • User defined thresholds for alerts and notifications.
Note - If external leads are needed for custom
placement, call a sales representative to
customize your order.

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