Product Review: Hanna Groline HI9814 Waterproof Portable pH/EC/TDS Meter
Why Measure pH/EC/TDS?
In various agricultural applications (particularly hydroponics), nutrient and pH management and the maintenance of scientific instruments are essential steps to ensure optimal plant growth and development.
The measurement of EC and TDS enables users to determine the nutrient quantity within a solution or soils, while it’s important to measure pH as it impacts plant nutrient uptake. Simultaneously measuring EC, TDS, and pH is a straightforward way to ensure optimal growing conditions and empower users to take corrective actions where required.
