Tds Monitoring

The nutrient solution and its management are the foundation of a successful hydroponics system. The function of a hydroponics nutrient solution is to supply the plant roots with water, oxygen and essential mineral elements in soluble form.

A test of the Total Dissolved Solids (TDS) using the DS Meter or pDS Meter or continuous monitoring with the HYDRO-STIK gives the grower accurate measurements of the concentration of nutrients in solution. If the concentration drops below the optimum level required to sustain and grow the plants, add more nutrientrich solution until the desired concentration level is achieved. This prevents haphazard dosing and wasted solution, which minimizes costs to the grower.

pH Monitoring

pH of the nutrient solution is also critical to successful plant growth. All elements have a specific solubility pH range. This means that mineral elements dissolve and can become more concentrated in solution within certain pH ranges. Roots absorb only the dissolved nutrients, so this is critical to plant growth. The TH1H and the pDS Meter quickly and easily measure pH.

Monitoring the addition of a pH balancing solution with the TH1H or the pDS Meter lets the grower precisely adjust the pH level. Beyond affecting nutrient availability, extremely low or high pH can even damage or kill plants.

All Myron L TDS and pH instruments give labaccurate results in the field. All Myron L instruments use advanced Temperature Compensation (TC) circuitry and equations to give you the best TC correction available.
