Abstract
The invention relates to an apparatus comprising a measurement chamber and a resonator, which can be integrated in the measurement chamber via a quick-action closure, for the liquid sensor system and for verification and measurement of the concentration of materials, substances, particles and/or microorganisms in liquids. The invention is characterized in that the resonator is held only on its outer circumference by a thin elastomer ring, and in that at the radial distance of the external diameter of the resonator, the elastomer ring on the one hand rests on an upper sealing ring of the measurement chamber, forming a seal, and on the other hand rests on a holding ring.
