Description
LAQUAtwin-K-11 Potassium Meter
LAQUAtwin-K-11 is a waterproof potassium meter with a large backlit LCD display. This equipment incorporates a flat ion electrode, unique in the world, designed with the latest HORIBA technology for micro-volume measurement.
The replaceable electrode makes use of the same measurement principle as the traditional potassium ion selective electrode (ISE); however, K-11 requires only a few drops (0.3 ml) to provide a fast and accurate analysis.
The potassium concentration of a solid sample can be easily assessed by placing the sample directly on the sensor. Measurements can also be made of samples such as liquids, pastes and powders.
On the other hand, K-11 can be used as a traditional potassium meter by immersing the electrode in a liquid. Finally, an absorbent paper allows us to analyse micro samples from 50 ul.
The wide measuring range of 4 to 9900 ppm (0.1 to 250 mmol/L) allows high concentrations to be measured without the need for dilution. The LAQUAtwin-K-11 does not use reagents.
The LAQUAtwin-K-11 potassium meter is reliable and very easy to use. It takes only a few seconds to give a result, making it an ideal instrument for analysis in the field.
LAQUAtwin meters are perfect for laboratory professionals and field technicians. This tool can be useful for decision-making when carrying out quality inspections, as it provides an immediate assessment of potassium concentration in many applications.
Some uses of the LAQUAtwin-K-11:
Food quality control, soil testing and plant sap analysis (to evaluate fertilization efficiency and crop nutrition), health monitoring.
Soil analysis (evaluation of the concentration of nutrients in the soil).
Plant sap analysis (to assess fertilization efficiency and crop nutrition).
Food analysis (fish, meat, vegetables…).
Saliva analysis.
