ERAVISC X is the worlds smallest and most rugged kinematic viscometer with lab-grade precision meeting ASTM D445 and ASTM D7042. Its revolutionary viscosity cell is combined with eralytics unique x-oscillating metal U-tube density meter allowing a simultaneous high-precision density measurement in full compliance with ASTM D4052 and ISO 12185.

The fully automated measurement of the kinematic viscosity at 40 C or at 100 C takes only 1 minute. Results are displayed on the large industry-proven color touchscreen and can be printed, exported via USB, or directly transferred to a PC or LIMS via Ethernet connection. With its unique sample introduction from the top ERAVISC X kinematic viscometer is equally easy to operate for right-handed and left-handed

ERAVISC X automatic kinematic viscometer is built in a corrosion-resistant aluminum housing. Its ruggedness and reliability make it the ideal solution for daily viscosity measurements in the laboratory as well as directly in the field to immediately detect contamination, mix-up, and oil degradation. ERAVISC X is the perfect solution for highly accurate testing even under extreme conditions.

ERAVISC Xs revolutionary capillary measuring cell is a real game-changer for high-precision kinematic viscosity testing at any temperature between 15 C and 100 C. Latest Peltier Technology allows for automated, high-speed viscosity index measurement. eralytics unique FillingProof™ solution detects even the smallest bubbles, ensuring maximum accuracy.

ERAVISC X is the kinematic viscometer with the smallest footprint on the market, still offering maximum ease of use and operator convenience. The compact dimensions and lightweight instrument design offer true portability on-site and require minimum bench space in the lab.

ERAVISC X allows for the independent measurements of viscosity and density enabling the simultaneous determination of both
values at different temperatures. eralytics unique capillary viscosity measurement method determines the flow time of the sample as a
function of a rapidly measured pressure. This patented principle combines the advantages of traditional measurement methods with the speed and ease of use of eralytics instruments.


features__astm compliantERACHECK is fully compliant with ASTM D2896, ASTM D445, ASTM D664, ASTM D7412, ASTM D7414, ASTM D7415, ASTM D7418, ASTM D7624, ASTM E2412, providing both standard method and refined methodology.
features__simple operatonAll eralytics analyzers use an intuitive menu structure that is easy to navigate. Samples need no prior preparation and measurements are done fully automated.
A direct out-of-the-box connection to LIMS (Laboratory Information Management System) is established with a standard Ethernet cable.No extra software or PC are necessary.
features__footprintThe small footprint of the eralytics instruments makes them the first choice for use in the lab and on-site.
features__touch screenAll Eralytics analyzer results are displayed immediately after the test on their large and user-friendly color touch screen.
features__portableThe Eralytics units are all lightweight and built with an integrated carrying handle, they are versatile and ideally suited for mobile applications as well.
