Durable. Dependable. Design you can trust.

The high-precision density meter ERADENS X.

ERADENS X is the world’s smallest and lightest D4052 high-precision density meter measuring in full compliance with ASTM D4052 and ISO 12185. It convinces with a rugged corrosion-resistant aluminum housing with most compact dimensions, still offering a large color touchscreen and a state-of-the-art built-in industry PC.

With its revolutionary vertically aligned x-oscillation metal U-tube design, ERADENS X is extremely reliable and rugged. Unaffected by shocks and vibrations it is also perfect for testing under extreme conditions like inside mobile labs.

ERADENS X provides density results with 5-digit precision. A unique full range viscosity correction ensures highest accuracy over the wide temperature range of 0 – 100 °C.

The vertical alignment of the U-tube minimizes the probability of air bubbles getting trapped inside the density cell. For the verification of the bubble-free filling, eralytics has developed FillingProof™. In contrast to error-prone optical methods, we use the change in the density as a function of applied pressure to detect even the smallest bubbles providing reliable results also for non-transparent samples such as crude oil.

The large color touchscreen and its unique sample introduction from the top make your daily measurement routine highly effective and equally easy to operate for right-handed and left-handed persons.
