Pro Model Coffee Refractometer & TDS Meter

Meet the newest member in our family of TDS meters. The original TDS meter gave readings to the 1/10th, i.e. a TDS reading of 1.6. The new pro-line cold brew & coffee TDS meter gives readings to the 1/100th, i.e. a much more accurate reading of 1.63. Now, creating a consistent product is even easier with the use of our pro-line TDS meter.
Our Pro-line Tea TDS Meter / Brix Refractometer gives you an accurate yet very affordable way for measuring your beverages (coffee, cold brew, tea, etc) total dissolved solid levels, and give you the confidence in knowing exactly what you are serving. 

What is a TDS Meter?

A TDS meter will give you a visual of how strong your coffee actually is.  TDS (Total Dissolved Solids) is a measurement used to tell you how much you have extracted from your coffee or tea. 

What Should My Cold Brew TDS Be?

To each is their own when it comes to making coffee.  But a good ready to drink cold brew in our opinion is typically around 1.6 TDS. As you start doing concentrates, this number will get higher.
