  • Sensor can “transmit now” using sealed power switch.
  • Rugged metal industrial enclosure.  Water and dust proof.  IP65.
  • Battery Life:  Appropriately 10 years when transmitting once per hour – so long that we call these wireless sensors Practically Battery Free™.*
  • See compact version of this sensor when industrial features or long battery life are not needed.
  • Humidity probe accuracy: +/- 1.8%* (10% to 90% RH)*.
  • Relative humidity operating range 0 – 100% RH*.
  • Relative humidity response time 8 sec (tau 63%)
  • Dew point is also reported but alerts cannot be set on the dew point.
  • Probe Length: Available with 6 or 36 inch tether.
  • Electronics Operating Temperature:  -40° to 85°C (-40° to 185°F)*
  • Chemical vapors at high concentration in combination with long exposure times may offset the sensor reading.
  • Radio range:  Up to 350 feet in open air.  Repeaters are available to extend range.
  • FCC, IC certified.
  • 915 MHz radio (North America).  Will not interfere with 2.4 GHz WiFi networks.  Contact us if outside North America.
  • Battery:  3V C-sized rugged battery pack designed for high vibration environments.
  • Sensor Size (in inches):  3.49 x 2.44 x 1.33 inches.  Antenna: 6 to 8 inches long.  Optional mounting tabs extend another 0.5 inches from both the top and bottom of the sensor.
