Instant Viscosity, Density and Temperature measurement for on-site lubricant and industrial fluid monitoring.
Product Description
The Yateks ViscoPen is a compact handheld fluid analyzer for rapid on-site testing of diesel fuel, lubricants and industrial fluids. Using piezoelectric resonant MEMS technology, it measures viscosity, density and temperature within seconds. Its pen-style portable design, IP67-rated probe and one-button operation enable fast and reliable fluid condition checks in the field. Protect your diesel powered equipment with immediate identification of paraffin adulteration.

Application:
Designed for industrial lubrication monitoring, Yateks ViscoPen is widely applicable to aerospace, oilfields, ports, transportation, mining, electric power, metallurgy, chemical engineering and construction machinery. It effectively avoids equipment wear and failure resulting from poor lubrication, realizes condition-based oil replacement, and reduces lubricant waste as well as potential equipment breakdown risks. Keeping pace with the industry trend of large-scale, heavy-duty equipment and intelligent operation & maintenance, it delivers high-precision lubrication data to support full-lifecycle equipment condition monitoring.
