Salinity Tester and 4 in 1 Hydrogen Water Tester, Digital Pool Salt Tester for Saltwater Pool and pH H2 ORP Meter for Drinking Water, Hydroponic, Aquariums

• Ciztada salinity tester has 2 measurement modes, scale range 0~9999 ppm/10.0~200 ppt and 0.00-25.00%, which is 2 times than the salinity refractometer.
• The Ciztada multi-parameter Tester can test Salinity, TDS, EC and Temperature in an accurate, quick and reliable manner for most regular water solutions' testing. Support One-tap switch from salinity to TDS/EC.
• Dual Hydrogen (H2) Modes for Optimal Health Our innovative hydrogen water tester boasts two H2 modes (ppb and ppm), delivering precise measurements of hydrogen concentration in drinking water. Ensure your hydrogen water generator is operating at its best, providing you with the benefits of healthy, hydrogen water for improved well-being.
• Precision ORP Meter for Testing Drinking Water ORP meter can accurately assess the oxidation of water and maintain the ORP value of drinking water between the optimal level of +300mV to +500mV, ensuring that you can drink tap water, filtered water or bottled water safely and healthily.
• Helpful for Hydroponic Systems Our pH ppm tester is designed for balancing pH and ppm in nutrient solutions, helping your hydroponic work. The Automatic Temperature Compensation (ATC) function ensures stable readings regardless of ambient temperature, making it a must-have tool for hydroponics, aquaponics, DWC systems.
