Density ρ, a characteristic property of materials, indicates the relationship of mass m to volume V.
Digital density measurement uses the U-tube oscillation principle. A measuring sensor (oscillator), is electronically excited to oscillate at its characteristic frequency. The characteristic frequency changes depending on the density of the filled sample. With a precise measurement of the characteristic frequency, the true density of the sample is determined.
Precise density measurements also require accurate temperature control and measurement, as during heating or cooling the density of the sample changes making precise density determination temperature-dependent.
The Density Meter EDM from SCHMIDT+HAENSCH sets new standards in the density determination of liquids in terms of performance and price delivering high precision measuring results.
SCHMIDT+HAENSCH is the world’s only manufacturer to offer a replaceable and pre-calibrated measuring cell.
