pH Meter for Hydroponic, 4 in 1 pH EC TDS Meter with Dissolved Oxygen Meter for Hydroponic, Aquairum, Aquaponic, Water

EZTOCH pH Meter for Hydroponic, 4 in 1 pH EC TDS Meter with Dissolved Oxygen Meter for Hydroponic, Aquairum, Aquaponic, Water

• Packing List: 4 in 1 pH EC TDS Meter, Dissolved Oxygen Meter
• Simultaneously display pH EC Temp or pH ppm Temp: This pH tester can display the measured values of pH EC and temperature at the same time. Press the MODE button can adjust to display the measured values of pH PPM and temperature Simultaneously; read 3 parameters at a time, which is easier to use; and this water pH meter has a lock function, whether it is used to measure hydroponics, drinking water or aquarium, you can easily lock and record the readings
• pH EC Meter for Hydroponic Growth: This pH meter can easily measure the pH and conductivity levels of hydroponic nutrient solution, and the conductivity measurement range is 0.00-19.99mS/cm which adopts a more practical 0.01mS/cm unit and a dual design of PPM 500 hydroponic unit. It is a 4-in-1 hydroponic pH EC TDS tester that is sufficient for hydroponic beginners and enthusiasts
• Digital Dissolved Oxygen Meter: Has two measurement units: mg/L (dissolved oxygen content per liter of water) and % (percentage of saturated dissolved oxygen). Test Range is 0.0-40.0 mg/L and 0.0-300.0%. Do Meter comes with a 3.6-ft (1.1-meter) electrode cable, making it easy to measure dissolved oxygen levels in small fish pond and also includes one bottle of zero-oxygen water calibration solution, two bottles of electrolyte solution, and six membranes, making it very convenient to use
• Digital Dissolved Oxygen Meter for Pond: For most aquatic life, oxygen levels must be at least 6 mg/L. Use a pond oxygen meter to monitor oxygen levels in aquariums, ponds, fish tank, koi pond, and goldfish ponds to ensure your ponds has enough dissolved oxygen to keep aerobic lifeforms happy
