M1421 Temperature Probe Calibration Reference

Post by briannez » July 11th, 2011, 2:02 pm

Hi there. We have a temperature probe model M1421 currently deployed at Project Neptune (University of Victoria). I am trying to compile some metadata about this probe but cannot seem to find the appropriate information. What I am looking to find out is the scale of reference this temperature probe is calibrated for. Is this probe referenced to the ITS-90 scale or IPTS-68 or some other reference scale? If someone could help me answer this question I would really appreciate it.

The M1421 has been obsolete for 8 years, but I was able to dig up some data that may be of assistance.

RTD Type: alpha = 0.00392, 100Ohm @ 0 degrees C.

The user manual that contains calibration information is located at the link below. I hope this can provide you with enough data to answer your question.
