Accurate enough, we’ll see how long that lasts!
Handy piece of equipment, quite literally. That little prove you need to measure surface temperature.

Can this probe be specially calibrated as a system with the HH42A to a specification of +/- 0.05 °C ?
Thank you for your question.
Although the ON-403-PP and the HH42A can be calibrated together, the accuracy would be the accuracy of the probe plus the accuracy of the HH42A so it can not be +/-.05C
