pH and Ec meters

Measuring instruments lets us supply the most suitable irrigation water to our plants with. In turn, plants respond by feeding well on the nutrients we give them. Checking temperature, acidity and salt concentration in irrigation water will make our plants healthier and, consequently, more productive.

Soil pH (acidity) determines if the roots can absorb nutrients efficiently or not. During the vegetative stage, pH must be about 5.5-6 so that nitrogen can be properly absorbed. On the other hand, pH must be between 6.5-6.8 during the bloom, so there is a proper phosphorous and potassium uptake. Meters let us determine the value of water acidity and correct it with acids.

Salinity or Ec concentration is linked to the amount of dissolved fertilizers, as well as other components. A base water with a high Rv is bad for irrigating since it lets us use barely no nutrients. Osmosis water is about 0.0 Ec, which lets the plant absorb all nutrients available. The Ec meter will let us know the amount of salts in the base water and how much fertilizer we must use to do the nutrient solution. The limits are about 800Ms during the vegetative stage and about 2.Ms during the bloom.

Water temperature is also important since the mixture of water and nutrients in the soil also includes oxygen. At 23°C water contains about 8.5p.p.m. which is the optimal level for a proper nutrient intake. A higher or lower temperature will result in an excess or deficiency of oxygen in the solution, which will hinder nutrient uptake and the yield.

Some meters such as pH-meters and Ec-meters by Wassertech and Milwaukee measure a single parameter. These are simple and economical instruments which serve their purpose. If we take care of them and don't damp them in excess, our meters will last a long time. They are easily fine-tuned with the help of a calibrating-liquid envelope and a small screw that we will have to tighten or loosen until we get a reading.

Submersible meters such as Adwa Ad11 and Ad31 or the ones by Hanna and Combo, give Ec, pH and temperature values of the water solution. If we drop them accidentally in the irrigation tank, they won't be damaged. If the probe breaks due to a hit or fall, it will not be a problem neither since we also sell spare parts for its replacement.

If you use an automatic irrigation system with a tank, what you might need is a continuous monitor. There are several models of continuous monitor such as Bluelab Guardian or Trimeter. Continuous meters feature screens with probes that take the measurements and don't turn off ever. They provide Ec and pH values of water in the tank continuously, along with temperature readings. Ideal for aeroponics and hydroponics or cultivation with coco substrate.

There are pH and Ec meters equipped with a probe to take measurements where the hand doesn't reach. We sell several models by several brands such as Hanna and Wassertech.

We also sell precise Ec meters such as Truncheon: very accurate instruments which don't need calibration. There is a model of Ec meter named Ec Shake Nutrient Maker which doesn't use batteries. It works by shaking it, through kinetic energy.

If you don't want to control pH or Ec yourself, you can get a controller. Kontrol pH adjusts the pH of your nutrient solution automatically by means of a pump which doses correcting acid and a probe which measures acidity continuously.

With the nutrient controller Kontrol you'll get to bring the dose of fertilizers to a preset value automatically and also control pH once you have added the nutrients. Depending on the power of the pump, a larger or smaller amount of nutrients will come out of the pump when it is activated. We usually turn it on every time we fill the nutrient tank.

In this section you can purchase any model of Ec and pH meter on the market from the best brands such as Hanna, Milwaukee or Bluelab, always at the best price. They appear in our catalogue of products along with a detailed description that explains their main features and instructions for use. You won't have any problem when it comes to choose it or use it when you finally received it at home.
