Hydramotion has released a viscometer designed for use in small-scale reaction vessels. The new Hydramotion RV-100 is an unlimited-range, research-grade device for the continuous measurement of dynamic viscosity in reaction vessels of any capacity. The narrow-bodied enclosure takes up minimal space at the top of the vessel, leaving plenty of room for ancillary equipment, eg for stirring, reagent addition or temperature measurement. The RV-100 is light enough to be fitted to a laboratory-sized reaction vessel without requiring additional support. The instrument is supplied with a standard conical joint for sealed connection to commercially-available apparatus, or alternative fittings can be provided on request. The sensor is a solid probe with no moving parts, bearings or seals. The standard sensor is constructed from 316 stainless steel, although other materials can be used if required. It is available in any length to suit different vessel sizes. Output includes a 4-20mA analogue viscosity signal and a serial data-link (RS422/485 or RS232). It is suitable for monitoring changes in viscosity during the course of a reaction, for example in esterification or polymer synthesis, and can be used either as a research tool or applied to a small-scale production facility.
