Selected User Reviews For Thomas 4040 Traceable Thermometer/Clock, +/- 1 degree C Accuracy

Not bad

3/5

but only a single point of calibration This is an excellent piece of equipment. THE CALIBRATION, ON THE OTHER HAND, IS A SINGLE POINT CALIBRATION. It is not calibrated over a range but rather at room temperature and 50%. This will not work if you require a calibrated thermometer that can be calibrated over a wide temperature range (think regulated industries). As a reference, however, it's perfectly adequate. br>br>In addition, the calibration date for certificate cert is 1 year and 7 months away. When this one expires, I'll probably buy a new one because I'm not sure I'll be able to send it in for calibration.

It never functioned properly

3/5

Why don't these seem to be accurate at all when it comes to measuring humidity? They say it takes time for the unit to settle in so that accurate readings can be obtained, but I tried two and neither of them did. I brought a certified calibrated unit from work for comparative use and this never arrived even with 10%. This isn't much better than a $10 toy when it comes to accuracy.
