Certificate of Calibration FAQs

Q) Should I calibrate the temperature sensors after they are installed?
A) Yes, it is always good practice to verify that the installation was done correctly and that the temperatures are reading accurately. If you did not need to add extension wire to a temperature sensor then the temperature accuracy will be within +/- 1ºF.

Q) Should I purchase the NIST traceable calibration certificate for the monitor as well as the temperature sensors?
A) If you are getting vaccines from the VFC program or other program where you have to supply a certificate of calibration, then absolutely YES.

Q) How long is the certificate good for?
A) The certificate is good for one year. Every monitor* is calibrated and shipped to order so the year is up on day it is shipped.

Q) How do I get my system recalibrated and obtain a calibration certificate?

A) There are several options of obtaining a certificate of calibration:
1) If your state accepts it you can calibrate the monitor yourself. Please see our Field Calibration Procedure for details.

2) Hire an outside calibration house to perform the calibration.
3) Return the monitor and sensors to us for calibration. Contact:
sales@temperatureguard.com for pricing.

Option 1 is probably the least expensive method. We can send you a simple, step by step, calibration procedure for you to follow. It includes a certificate for you to complete and keep for your calibration records.

Option 2 is most likely more expensive than option 1. The calibration house would follow the same procedure in option 1) and supply you with the certificate.

Option 3 Temperature Guard can perform the calibration in less than 5 days. You will have to return the monitor and sensors for calibration. This is a good option if you have a small number of sensors with no extension wire.

Please note that it is always more accurate to calibrate the system in place because this will calibrate the complete system.
