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.
