Review on 🔍 Hanna Instruments Checker Copper Colorimeter: Accurate and Efficient Copper Level Measurement Device by Jerome Pritchard

I isolate fish all the time and have used this a thousand or more times, this is by far the best way to pinpoint ionic or chelated copper and other blanks test and other uses. It's very accurate and consistent. I have no idea how anyone can have trouble with reagent powder packets after they have been used for the first time, cut along the lines and compressed into a pouch. I have a YouTube video of how to use this product on my channel (4FordFamily).
