These Daiggger Scientific Brewery Test Kits use drop count titrations and color comparator to assess the Alkalinity, Calcium, Magnesium, Chloride, Sulfate, and Sodium concentrations of the Water. The Stout version also assesses the Alkalinity, Calcium, Magnesium, Chloride, Sulfate, and Sodium concentrations, but additionally, allows the brewer to look a little deeper adding 2 meters, the Myron L PT5 and the Oakton PTTestr 35, to test for pH, temperature, Total Dissolved Solids (TDS), and Dissolved Oxygen (DO). Both kits are packaged in durable plastic case with handle for easy transport and features unique EndPoint ID test procedures with photographic, step-by-step instructions for simplified testing.
