Bluelab PH & EC Meters for optimum plant growth

Bluelab has more than 30 years of experience in the production of robust and reliable testers and accessories for nutrient solutions for the hydroponic industry. The Bluelab products measure parameters such as pH, conductivity (EC or ppm) and temperature.

Bluelab meters and monitors are made in New Zealand and distributed worldwide. Our specialists have received full training from Bluelab.

What is PH

PH, an abbreviation for potential hydrogen, is the measurement of the acidity in a solution. A neutral pH is 7.0 pH.

Why is pH important?

It is important to maintain nutrient solutions at pH value, with the elements in the nutrient solution always being available to the plant. If the solution is too acidic or too basic, the nutrient uptake of the plant can 'get stuck'.

The elements that we add to a solution increase or decrease the pH measurement of the solution. Only an accurate measurement of the pH level gives complete control over the outcome.

What is conductivity?

Conductivity (measured in ppm, EC, TDS, CF) is the total soluble salts contained in a liquid solution. Pure water contains no salts, so it has a conductivity measurement of zero. By adding soluble elements to the water, electricity can move through the solution, giving it a conductivity score.

Why is the EC important?

For each crop there is a range in which the nutrient solution is optimal. Sufficient nutrient for growth and flowering, but not so strong that the concentration of salts in the plant becomes too high. Electronic meters are available to measure the conductivity of the nutrient solution.
