Monnit wireless temperature sensors use a thermistor to accurately measure temperatures. These sensors are perfect for monitoring ambient temperatures around the sensors physical location. User customization allows you to set the frequency of readings and the ability to set thresholds for alerts via SMS text and/or email.
Industry leading 25 month NIST certified product available on leaded temperature sensors. (In the Customize section above, select your probe length above then select NIST Certified.)
NIST certified sensors orders may take up to 6 weeks to prepare, certify and ship.
Already have NIST certified sensors and now need to renew the certification?
Monnit Industrial Sensors come in an IP65, NEMA 4X, CE rated, sealed, and weatherproof enclosure. They are powered by a single, replaceable, Industrial grade 3.6 V battery (included).
An optional solar powered version is also available. The solar powered version includes a Lithium Iron Phosphate rechargeable battery in conjunction with a solar power cell to keep the battery charged and at optimal capacity. If there is no light present at the solar cell, the battery alone could continue to power the sensor for up to 5 years.
If ordering NIST certified temperature sensors orders may take up to 6 weeks to ship.
* Actual range may vary depending on environment.
** Battery life is determined by sensor reporting frequency and other variables.
