1.Hydroponic EC pH Meter: Maintaining the correct EC pH is essential for plant growth. In general, the ideal pH range for hydroponics is 5.5-6.5, while the EC range is 1-4 or mS/cm. The pH Monitor helps you monitor this range 24 hours a day to ensure your plants are always absorbing nutrients optimally and thriving 2.SMART WATER MONITOR WITH DIGITAL pH METER: If you use a digital meter for testing, you need to manually measure the value every time. However, a smart water monitor is simpler and more accurate than a water meter, and by placing it in the water for just a few seconds, you can get 24 hours of data, saving you more time and money in the long run. 3.DATA RECORDING and EXPORT: The pH meter for water hydroponics can record hourly/daily/weekly/monthly changes in water quality; you can also download this data for statistical analysis of nutrient consumption. This allows you to replenish the nutrient solution in time to ensure the vigorous growth of hydroponic plants.
