MUST Liquid pH Aquarium Water Test Kit

FEATURES -7-in-1 Salinity Tester: This tester integrates 7 functions: PH, EC ( S/cm), TDS (ppm), salinity (ppm/%), S.G., and ORP (mV). The titanium sensor ensures accurate, rapid measurements. -Key Features: Auto temp compensation minimizes errors. IP67 waterproof for dust & leak protection. LCD backlight for clear readings. Auto-shutdown after 5 minutes. -Ease of Use: Portable, lightweight, with one-button mode switching and data locking. -Testing Modes: Supports salinity (0-9999 ppm), seawater (10-200 ppt), and food (0.01-25%) tests. Switch modes for accurate TDS/salinity readings. -Applications: Suitable for pools, spas, aquaculture, sewage treatment, education, healthcare, aquariums, and ocean monitoring.
