Viscometer model DV-I Prime
 


A continuous sensing capability for rapid viscosity measurement makes this economical digital viscometer a standout. Measures viscosity and temperature simultaneously (with an optional temperature probe). With its timed measurement function, data can easily be sent to a PC or printer. Optional software allows the DV-I Prime to collect, analyze and record test data.

Features
  • PC Interface for use with optional Wingather Software and output connection to printer
  • Direct access to time measurement function (time to torque, time to stop)
  • Temperature off-set capability to ±5°C
  • Senses and displays continuously:
    • Viscosity (cP or mPa·s)
    • Temperature (°C or °F) (OPTIONAL)
    • % Torque
    • Speed (rpm)
    • Spindle used
  • Torque measurement accuracy: 1% of full scale range
  • Repeatability: 0.2% of full scale range
  • Select all functions from user-friendly keypad
  • Choice of 18 rotational speeds
  • Optional RTD temperature probe
  • Auto-zero function to ensure precision torque measurement
  • Auto-range function to define full scale range (FSR) for all spindle/speed combinations
  • Warns of under- or over-range torque measurement condition
  • Direct output to chart recorder
  • Timed Stop feature to measure viscosity at precise user specified time interval
  • Time to Torque feature to measure the time interval for sample to reach user defined torque value
  • Compatible with all Brookfield accessories
  • NIST traceable viscosity standards available
