Liuyifei Digital pH Aquarium Water Test Kit

Product Description The 7-in-1 Water Quality Tester C600 is a professional multi-parameter testing pen engineered for fast, accurate, and reliable water analysis across a broad spectrum of applications. From freshwater aquariums and marine reef tanks to hydroponic systems, drinking water, and swimming pools, this compact instrument delivers precise measurements at the push of a button. Seven Key Parameters – One Compact Device This single pen measures all seven essential water quality indicators: pH: 0.01 – 14.00 pH – determines water acidity or alkalinity levels TDS: 0 – 10000 ppm / 10.1 – 200.0 ppt – measures total dissolved solids content EC: 0 – 10000 µS/cm / 10.01 – 19.99 mS/cm / 20.1 – 400 mS/cm – evaluates electrical conductivity and nutrient levels Salinity: 0 – 10000 ppm / 10.1 – 200.0 ppt / 0.00 – 25.00% – essential for saltwater and brackish water monitoring Specific Gravity (S.G.): 1.000 – 1.222 – tracks seawater density (typical marine range: 1.020 – 1.070) ORP: 0 – ±999 mV – measures oxidation-reduction potential for water quality assessment Temperature: 0.1 – 60.0°C / 32.0 – 140.0°F – ensures automatic compensation for other readings User-Friendly Design Simple one-button operation – press MODE/CAL to switch between all seven functions instantly Automatic Temperature Compensation (ATC) guarantees stable and accurate pH readings regardless of water temperature fluctuations Large, backlit LCD screen displays results clearly for easy reading in any lighting condition Powered by 4 LR44 button batteries for long-lasting performance Built to Last Rated IP67 waterproof and dustproof, this tester withstands temporary immersion and operates reliably in wet or humid environments. The durable pen-style housing (183 x 37 x 37 mm) weighs only 90 grams, making it highly portable with a built-in lanyard hole for convenient carrying. Versatile Applications This all-in-one tester is ideal for: Freshwater and saltwater aquarium maintenance Marine reef tank and coral system monitoring Hydroponic nutrient solution testing and adjustment Drinking water and tap water quality screening Swimming pool and spa water analysis General water purification system performance checks Educational and laboratory demonstration use What's Included 1 x 7-in-1 Water Quality Tester C600 (with 4 LR44 batteries pre-installed) 1 x User Manual pH calibration buffer powder packets Care and Maintenance Tips Rinse the electrode with distilled or clean water before and after each use Gently wipe the electrode dry and replace the protective cap after use Calibrate the pH function regularly using the provided buffer powder for optimal accuracy The device is IP67 rated for temporary immersion only – do not leave submerged for extended periods Maintain optimal water conditions with confidence. The C600 7-in-1 Water Quality Tester gives you all the critical data you need in one easy-to-use, portable device – perfect for hobbyists, professionals, and everyday water quality monitoring.
