The Horiba Laquatwin conductivity tester is a compact measuring device for quickly determining the electrical conductivity (EC value) in liquids on site. In horticulture, this value is a key indicator of the nutrient supply, as it provides information on the concentration of dissolved salts - such as nitrate, potassium or magnesium - which are essential for plant growth.
Importance of conductivity in horticulture:
Electrical conductivity is closely linked to the fertilizer concentration in the irrigation water or substrate. An EC value that is too low indicates an undersupply, which can lead to deficiency symptoms and growth disorders. A value that is too high, on the other hand, can indicate overfertilization or salinization, which inhibits the plants' water uptake and can lead to damage to roots and leaves. Regular monitoring of conductivity enables precise control of the nutrient supply and therefore makes a decisive contribution to plant health and yield stability.
Accordingly, the electrical conductivity (EC value) provides information about the total concentration of dissolved salts (fertilizer salts) in a solution. In horticulture, it is decisive for:
- Nutrient control: An EC value that is too low indicates a lack of nutrients, one that is too high indicates over-fertilization - both can impair plant growth.
- Irrigation management: EC helps to detect whether irrigation water or drainage water has too high a salt concentration.
- Substrate evaluation: In soil, coco or rock wool, the EC value indicates whether the substrate is too high or low in salt.
The Laquatwin conductivity pocket tester from Horiba offers the following applications in horticulture:
- Checking the nutrient solution during irrigation:
The tester can be used directly to test irrigation water or nutrient solutions. This ensures that the plants are not over- or under-fertilized.
- Analysis of the soil or substrate extract:
With the help of distilled water, a so-called 1:2 extract can be created from soil or substrate, the conductivity of which allows conclusions to be drawn about the salt concentration in the root zone.
- Monitoring in hydroponic systems:
In hydroponic systems, monitoring the EC value is particularly important, as plants there are supplied entirely via the nutrient solution. The Laquatwin allows quick, selective measurements directly in the system.
Advantages of the Laquatwin tester:
- Compact design: Ideal for mobile use directly on site.
- Small sample quantity: Only a few drops of liquid are sufficient for a measurement.
- Fast results: A measured value is available in just a few seconds.
- Easy to clean: The sensor surface can be easily rinsed off, allowing it to be reused quickly.
Conclusion:
The Horiba Laquatwin conductivity tester is a practical tool for gardeners, nurseries, horticultural managers and hobby growers. It helps to control the nutrient supply in a targeted manner, optimize plant growth and thus optimize or increase yields.
