Say goodbye to the colorimetric errors of traditional test strips. this electronic pool water tester eliminates guesswork and is ideal for maintaining a safe swimming environment at home. Easily monitor chlorine levels in tap water or pool water to effectively prevent skin irritation caused by improper chlorination. Whether for residential pools, hot tubs, or drinking water chlorine testing, the GIDIGI Water Tester provides accurate data. Regarding packaging: Batteries are sometimes placed under a white plastic inner tray.
• [Salinity, pH, and Chlorine Meter for Seawater Pools] The GIDIGI Multi-Functional Salinity Meter is optimized for seawater pools, accurately measuring salinity within an ideal range of 2700-3400 ppm, thereby improving chlorination reactor efficiency and preventing adverse situations caused by excessively high or low salinity. This pool salinity and chlorine testing kit is also suitable for seawater aquariums and brine solution testing. Whether you maintain an in-ground pool, above-ground pool, or spa, its salinity, pH, and chlorine readings ensure water chemical balance, providing a comfortable swimming experience and reducing equipment maintenance costs.
• [GIDIGI Salinity & TDS Meter for Aquariums and Fish Tanks] The ideal choice for aquarium enthusiasts! Maintaining stable water quality (TDS < 10 ppm) is crucial for delicate fish in saltwater or freshwater tanks. Its instant readings quickly verify the effectiveness of reverse osmosis water purifiers or the pH balance of the aquarium. Whether it's a reef tank, koi pond, or planted aquarium, this aquarium water quality analyzer prevents harmful fluctuations and is an essential tool for every aquarist.

Measure pool chlorine levels one second, and saltwater salinity the next—no need to change probes; one pen covers all scenarios. Whether for RV travel, pool maintenance, aquaculture, or agricultural planting, it's your reliable portable water quality tester.
• [EC and pH Meters for Hydroponics] EC (Electrolytic conductivity) and pH are key parameters determining plant health. Monitoring the EC concentration of the nutrient solution ensures that hydroponic plants such as lettuce, herbs, tomatoes, and strawberries absorb the appropriate amount of nutrients; pH testing helps to keep the pH within the optimal absorption range (typically 5.5–6.5). Let the data speak for itself, say goodbye to guesswork about fertilization.
