04721-000-00 - Multi Range Viscometer (ASTM D445)

Designed as a stand-alone instrument that requires no external PC for operation, the Herzog HVM472 Viscometers determines automatically the kinematic viscosity from 0.5 to 5000 mm2/s (capillary depending) while meeting or exceeding the requirements of ASTM D 445.

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.


- Quick, easy operation in three simple steps
- Performs two tests at two temperatures, simultaneously!
- Truly continuous operation with unique autosampler
- Results in five minutes
- 0,5-5000mm2/s range (depends on the measurement range of chosen capillaries)
- Stand alone operation
- Multi-instrument networking and enhanced PC-based operation with IRIS software platform
