About this item

• pH and EC Salinity Meter Combination: The GIDIGI 5-in-1 pH meter helps you monitor your reefs and gardens, ensuring your saltwater aquariums or hydroponic systems thrive. Aquarium enthusiasts can quickly read the pH and salinity of their reef tanks without changing meters, while the pH/EC meter helps hydroponic growers maximize the use of every drop of plant nutrient solution. The large, backlit color screen is easy to read even in dimly lit growing tents or sunny backyards, and allows for one-touch switching between pH, salinity, EC, TDS, and temperature.
• Multi-functional Pool Salt Meter: Save Your Pool and Spa – Say Goodbye to Guessing and Enjoy Swimming: Is your pool water cloudy or stinging your eyes? The cause is usually high or low pH and salinity. For saltwater pools with chlorination generators, you need a salinity of 2700-3400 ppm to produce chlorine. The GIDIGI salinity meter helps pool owners determine when to add pool salt. The ideal pH range for pool water is 7.2-7.8, ensuring clear and transparent water.
• Perfect for Coffee and Food Fermentation: The ideal water quality for brewing coffee is approximately 150 ppm TDS + neutral pH 7.0. The GIDIGI TDS meter combined with a water pH meter allows you to enjoy delicious coffee anytime. Making pickles or marinated vegetables? Salinity determines whether they will ferment or rot. Precise pH values ​​are not only used for brine fermentation but also for craft beer brewing and cheese making. This pen eliminates the need for complicated test strips, freeing chefs and bartenders from guesswork in the kitchen and brewery.
• Calibration Accessories and Automatic Temperature Compensation (ATC): This GIDIGI water quality testing pen eliminates manual adjustments! The pool pH meter features built-in temperature compensation (32.1-140℉) and a calibration accessory set (pH calibration and 12.88 mS/cm calibration), ensuring laboratory-grade accuracy in brine pool and digital hot tub water testing applications. The included test kit and four extra AAA batteries significantly reduce your maintenance costs. Easy to operate: Simply immerse the probe of the 5-in-1 tester into pool water or a sample cup and observe the results.
• A versatile and multifunctional pH meter:Measures pH: 0-14, salinity: 0-100.0 ppt (automatic ppm/ppt switching), EC, TDS, and temp. Easily handles various liquids from freshwater to seawater, from kitchens to laboratories, meeting the testing needs of users in different scenarios: swimming pools, hot tubs, spas, marine aquariums, freshwater tanks, planted aquariums, hydroponic systems, soil irrigation, drinking water testing, reverse osmosis water purification systems, craft beer, homemade pickles, yogurt and cheese, formula preparation, coffee brewing, outdoor streams, pond ecosystem maintenance, aquaculture, commercial greenhouses, laboratories, and food processing.
