Laboratory potassium concentration measuring system
Description
LABKAM is designed as a potassium content measuring device for laboratory use and measures the natural beta radiation.
A plastic scintillator is used for this.
In contrast to the counter tubes (Geiger counter), there is no need to protect the tube filled with ionizing gas.
This gives the device more mechanical resistance to e.g. Vibrations.
Even if the amount of material is not corrected, it is absolutely necessary to keep the distance between the detector and the measuring surface constant by evenly filling the sample trays.

Measuring principle
The radiometric determination of the potassium content can in principle be carried out in two ways: measurement of the γ or β radiation.
The γ-measurement requires either a considerable amount of material to address the detector or additional measurement to correct the changed amount of material.
With the β-measurement, the thickness of the saturation layer is less than 5 mm and no quantity correction is required.
By measuring the radiation of the natural isotope K40, one can determine the potassium content - based on the constant half-life and equal distribution of the isotope.
This can be done using two working modes:
● Measurement via the microcontroller - all necessary steps are controlled via the membrane keyboard of the microcontroller and results are read on the display.
● Measurement via PC with Windows - All necessary steps are controlled on the PC with special measurement software and results are output on the monitor. The microcontroller only transmits the recorded data, but does not carry out any calculations.
