The DensX measures mud densities between 1.0 T/m³ and 1.4 T/m³ with an accuracy of 0.25 %.

The technology is based on X-ray and is a direct measurement method.

The X-ray technology does not suffer from strong
legislation restrictions like radioactive density measurement systems.

With a sampling speed of 10 Hz the system supports fast
