I've been using the r2 mini since July and am looking to upgrade to something more accurate/higher resolution/better all around. Do the Myron L Ultrameters fall into your opinion of conductivity meters or are they a real step up? Seems like there should be a HUGE difference between a $16 tds meter and an $800 Ultrameter II. I'm also curious about your background in coffee and these analyses. I've been seriously studying brewing and roasting for about a year now and just got SCAA certified as a GC brewing technician and am trying to build a lab. Hey David,

Well, hopefully i can just convince my cafe's owner to purchase one for us! Thanks for the advice! I want it not to be so though!

You can of course pick up one of the cheap ebay TDS meters (conductivity meters) and give it a go (for coffee, not espresso). Personally having used a mojo refractometer for the last 8 months or so, I couldn't go back to a conductivity meter. I'm not sure about other (cheaper) refractometers. I believe there are specifications in the mojotogo literature re compatibility. The refractometer has to read at a certain wavelength and be able to report nD and temperature. The resolution of the specific refractometer will then determine the accuracy (more resolution required for coffee than espresso). Hey Collin.

Any specifications/a specific one you would recommend? Cheers, Collin Hey David,

Maybe a little tutorial on what you have found to be the best process of using it would be a great blog post? We’ve ordered the $16 TDS meter and have been awaiting its arrival for a while now.
