Herzog's HVM 472 Automated Multi-Range Viscometer measures transparent and opaque liquids in as little as two minutes with a unique dual-bath design that enables two simultaneous tests at two temperatures. Plus, a revolutionary auto sampler offers truly continuous operation: spent sample cups automatically discharge, allowing you to add new samples at any time.... even mid-test! The HVM 472 and HVM 472 FR meets or exceeds precision requirements of ASTM D 445. 

Results can be exported to a printer or LIMS. Add Windows-based HLIS (Herzog Laboratory Information System) software for enhanced operation and data management.

Truly continuous operation...

Each of the two independent baths is supplied sample by its own 26-position auto sampler or by a single feeding station (shown at right). Preload a total of 52 samples for automated testing. During operation, this unique sampling system feeds the capillary, spent discharged sample cups and allows you to insert new samples... even while another sample being tested! As new cups are added to the feeder, this smart system automatically prompts you for a sample name and ID, incorporating it into the programmed test routine.
