pH meter
In this section you will find various pH meters. With the devices you will find in this section you can measure the pH with a range of +-0.5 in the pH value. The measuring strips are the easiest to use, just dip the strip into the solution to be measured and compare the result with the standard table on the box. The digital meter also allows you to measure easily, although it is advisable to calibrate before use.

Super Absorbent Polymers
Super Absorbent Polymers belong to a group of polymers capable of absorbing large amounts of water or liquid (100, 200, 300 times their weight in water). These polymers when absorbing water form a gel that gives them properties for a wide range of uses. Current uses of Super Absorbent Polymers range from agriculture to the cable industry. In Alquera we work with a wide range of super absorbent polymers that you can find below: hydrogel or potassium polyacrylate: for agriculture, for water retention for plants, sodium polyacrylate for all kinds of applications where you need a liquid retention, gel balls, for decoration and water endowment for potted plants and artificial snow (sodium polyacrylate based, but modified), which is used in snow decorations and science experiments for children. You can see more information about each of them by clicking on each image.
Fluorescent Tracers
Fluorescent tracers have become one of the most effective methods in the field of hydrology, used for leak detection. They are used for
Fertilisers and phytosanitary products
Agricultural fertilisers, mainly straight and soluble fertilisers, and also NKP compounds. Plants need macro nutrients (nutrients they will need in larger quantities) and micronutrients (they will need them in very small quantities or as traces). Within the macronutrients there are mainly the 3: Nitrogen (N), Phosphorus (P) and Potassium (K), they also need in somewhat smaller proportions Sulphur (S), Calcium (Ca), Magnesium (Mg). As micronutrients we have small traces of iron (Fe), copper (Cu), zinc (Zn), boron (B), manganese (Mn), chlorine (Cl) and molybdenum (Mo).
