Poniie PH2022Plus Waterproof Digital PH Meter for Water Hydroponics Food Brewing w/Portable Toolkit Combo, 0.01 Resolution

• pH Meter: You can use a pH meter to check the pH of your water, mash, [test Star San effectiveness] and finished beer.
• TDS Meter: TDS meters can are helpful for brewing if you’re using a RO filter or if you purchase RO (reverse osmosis) water for brewing.  If you’re using an RO filter a TDS meter tells you how effective your filter is and can help you know if your filters need to be replaced.  If you buy RO water, a TDS meter can let you know what you’re getting as some water processors add minerals back for flavor.  A TDS meter will allow you to make sure you’re getting what you want.
• Thermometer: You can use a thermometer to… measure temperature. 🙂
