We have a range of temperature measuring devices on our site. As per many places, we send off one temperature probe for annual external calibration and then calibrate the others against it.
I would like to do the same with our ibutton dataloggers, but I've not been able to find any information about an accepted method for doing this.
Does anyone already do this who could help me or point me in the direction of a method? We use them in the range of 100C to -18C.
Thank you very much!
