Fluke 8845A VS Keysight 34461A opinions
« on: October 17, 2017, 08:52:47 pm »
Hello all!  I would love opinions on these two benchtop multimeters.  FLUKE 8845A VS KEYSIGHT 34461A.  The meters will be used in metrology - not in a "hobby" type of environment although metrology is my hobby. I will mention that the Fluke is approximately $150 USD less expensive.  I have gathered quotes on getting the items calibrated and the cost is approximately the same for both of them.  I do like the TEMP feature of the fluke 8845A as the meter will also be used to monitor a PRT.  Does the 8845 allow for entry of ITS-90 coefficients or only CVD coefficients?  I have a Fluke 5627A probe that I will be using.  The meter will also be used to measure current from transducers.  This meter will honestly be the workhorse for a lab so stability matters, along with usability.

Thank you and I look forward to your opinions.  I especially would love to hear from some of you who have owned both of these units, but if anyone has owned even one of the units please let me know your positives and negatives.

I have searched the forum for direct comparisons and while they may have been indirectly compared I have not seen a recent discussion on these two models.

I had the same choice and I went for the 34461A because it can do things like trend charts by itself, save a screendump to USB etc. All in all the 34461A is a more modern instrument with the same specs. You might need the 34465A though for use with PT100 elements because IIRC the 34461A can't use these.
There are small lies, big lies and then there is what is on the screen of your oscilloscope.

Thank you nctnico for the advice.  The charting features are not that relevant to me, and after researching I believe you are correct that the 34461a may not perform as a prt readout in the manner that I would like it to.  I spoke to Fluke today and the 8845A will also not be the best option - the 8846A would be better for what I am trying to do as it allows storing of PRT coefficients etc.  I think the best route to go may be to buy the less expensive of the DMM and find a dedicated resistance readout for the PRT.

Thanks.
