The Labmart LMDV100 Digital Rotational Viscometer is a digital direct-reading rotational viscometer designed to measure the absolute viscosity of Newtonian liquids and apparent viscosity of non-Newtonian liquids. It features a 12–6,000,000 mPa·s measuring range, 0.1–99.9 speed range, Auto Range function, temperature monitoring, LCD display and RS232C output.

3. Detailed Product Description

Product Overview

The LMDV100 Digital Rotational Viscometer is part of the LABMAN LMDV series of Digital Direct Reading Rotational Viscometers. It is designed for measuring the absolute viscosity of Newtonian liquids as well as the apparent viscosity of non-Newtonian liquids.

The LMDV100 provides a broad measuring range of 12 to 6,000,000 mPa·s and a selectable speed range of 0.1 to 99.9. The catalogue specifies 1000 speeds and selectable stepless speed operation.

The instrument provides direct viscosity and temperature display, an Auto Range function, temperature monitoring and a big ultra-bright backlight LCD display.

The standard configuration includes four spindles — L1, L2, L3 and L4 — along with an RTD probe, spindle guard and wrench, indicator stand and other standard accessories.
