## Description

TDS Refractometer for Coffee R2 Extract, Range 0-30%, Accuracy ±0.02%, Portable, Water Resistant, Rechargeable, Ideal for Drip Coffee, Espresso and Coffee Enthusiasts : desertcart.co.uk: Business, Industry & Science

Review: Great tool, quick use. Contrary to other mentions I never have to recalibrate - I used distilled water and my water, both same result and stability. My only complaint is that my measurements fluctuate when my sample is cooling down. I do like the little spoon it does help to mix and take a proper sample and cool it a little.
Review: The R2 Extract Coffee TDS Refractometer is quite precise, user-friendly tool for serious coffee enthusiasts. With a 0–30% range and ±0.02% precision, it provides accurate readings for espresso, pour-over, and other brews. Its compact, waterproof design and rechargeable battery make it convenient for both home and café use. The interface is straightforward, and readings are quick and reliable—perfect for dialing in recipes or tracking brew consistency. It's a valuable tool for anyone wanting to better understand extraction and improve cup quality. A great investment for those who take their coffee seriously. Its quite an investment and it could have a more durable construction although it feels sturdy. A durable hard storage case to preotect it would be a plus over the soft case.

Imma go 5 stars for. 1. Great product works as described. Integrates with their scale perfectly. 2. Easy to set up. Really gets your coffee game up to speed for a better cup in no time. Learn how grind size can make a huge difference.. Customer service is Top notch. I had issues with their scale. Got me in the right direction ASAP Because of this I bought the R2. No regrets... Buy it it's a great piece of gear.. Works for espresso as well.. Enter the numbers the amount of coffee you brewed. The weight of the cup .. it does all the work It would be nice if they had a chart on how to dial in sour or bitter coffee. But easy enough to get the info on the web. Kudos
