Product Details

Perfect pH control for various media - ph meter for water hydroponics can be used for growing tents, swimming pools, drinking water, aquariums, fish tanks, and brewing. Our pH meter provides a quick and handy way to manage the success of your crops. Helps you ensure that pH and temperature are always in the optimal range for maximum uptake of nutrients. *Note: readings in tap, reverse osmosis (RO) or distilled water may be slow and/or unstable due to insufficient dissolved Ions (salts).
Easy calibration - Set up our digital pH meter with a two-point calibration process. Calibrate the handheld meter before first use. Each digital pH meter for soil and water comes with a 30-day calibration indicator that can be viewed on a backlit LCD display. The kit includes one 20-ml sachet of each pH7, pH4, and KCl for initial hydration and calibration.
Get accurate readings with a double-junction probe. Unlike glass bulbs, the double-junction probe minimizes contamination. Hence, it helps in improving precise readings and has a longer lifespan. This pH pen has automatic temperature compensation for an accurate temperature. Our pH meter for water hydroponics will take measurements in increments of 0.1 pH.
