Rotational Viscometer LVM-A42

Rotational Viscometer LVM-A42

Rotational Viscometer LVM-A42 has a 0.3 to 100 rpm speed range with ±1% measurement error.  It measures the viscosity of liquids and semi-solids at specified shear rates. Its advanced ARM technology and built-in Linus system ensure stable and accurate results. This device provides high measuring precision with minimal error. It offers a wide variety of vicious range with multiple speed options for flexible testing. The real-time viscosity curve display helps analyze shear rate and viscosity variations. Our rotational viscometer is a floor-standing rotational viscometer designed for precise viscosity measurement.
