 Temperature-Controlled Laboratory Viscometer w/Choice of Piston Range   BTVR-15   $13,043.00      
  This viscosity technology is based on a simple and reliable electromagnetic concept. Two coils move the piston back and forth magnetically at a constant force. Proprietary circuitry analyz0es the piston’s two-way travel time to measure absolute viscosity. Built-in temperature detector (RTD) senses the actual temperature in the sampling chamber. Constant in and out motion keeps samples fresh and mechanically scrubs the sampling area.

The Temperature Controlled Laboratory Viscometer contains a piston-style electromagnetic sensor and RTD that provides continuous viscosity, temperature and temperature compensated viscosity (TCV) readings. Measurements can be made in any of thirteen 20:1 viscosity ranges and temperature can be displayed in °C or °F. One factory-calibrated piston accompanies each system. Please specify the piston range from the list below when ordering or contact us at 740-549-9386.

Integrated temperature control allows user defined measurements at any setting from slightly above ambient to 180°C (356°F). The sensor is easily field calibrated. Multiple operating ranges can be pre-calibrated.

Data can be output to a PC via the RS-232 serial port for tracking, storage or graphical display. The electronics allow the user to define TCV equation values, data averaging interval, alarm points, density and much more.
