The LMDV111 Digital Viscometer with Small Sample Adaptor is a digital direct-reading rotational viscometer designed for measuring the absolute viscosity of Newtonian liquids and apparent viscosity of non-Newtonian liquids. It combines a wide 12–6,000,000 mPa·s viscosity range with a dedicated small sample adaptor requiring approximately 10–20 mL of sample. 

Product Overview

The LABMAN LMDV111 Digital Viscometer with Small Sample Adaptor is a digital direct-reading rotational viscometer specifically configured for viscosity measurement where a smaller sample volume is desirable.

The LMDV111 provides a measuring range of 12–6,000,000 mPa·s, selectable stepless speed from 0.1 to 99.9, and 1000 speeds. It provides direct viscosity and temperature display through an LCD and includes temperature monitoring.

The supplied Small Sample Adaptor is a standard accessory. The catalogue describes it as consisting of a coupling nut, extension link, spindle set #21, #27, #28 and #29, sample chamber and adjustable base. The catalogue specifies approximately 15 mL sample requirement in its product description, while the specification table gives a minimum sample range of 10 mL–20 mL.

The sample chamber fits into a water jacket, and sample temperature can be controlled using an optional Refrigerated Circulating Bath.
