A NIST sensor is an external calibrated temperature probe that you can connect to your Z sensor on either port one or port two. The Z sensor allows for up to two NIST sensors to be connected at one time via the two available ports. The process for a new NIST sensor and a replacement sensor is similar.
​
All SmartSense Z sensors can be provided with a traceable calibration certificate that meets the requirements of and complies with ISO 17025. The traceable certificate indicates that the product is traceable to standards provided by the National Institute of Standards and Technology (NIST), a U.S. Government agency within the Commerce Department.
​
Customers commonly require this in the health/medicine field or anyone who requires a higher level of proof of accuracy on their sensors.
​
Below are examples of SmartSense NIST probes that are compatible with the Z sensor.

The NIST calibration process is provided via a removable, and replaceable NIST calibrated temperature and/or humidity probe. This probe is installed in one of the external ports of your Z sensor. The companion NIST calibration certificate will appear in your SmartSense account automatically.

You can find more information about accessing the calibration certificate here.
​
Recalibration services are available by ordering a new NIST-calibrated probe with a new 24-month term.

לפני שתתחיל בהתקנה, ודא שברשותך:

You may also have NIST humidity and temperature sensor envelopes which will be sealed. Please do not discard.

Unscrew the port cover cap then skip to step 2 of Sensor Replacement.

Note: While usually one probe is used, it's possible to use both ports simultaneously if you require another type of calibrated probe.
