Viscometer Heating Baths

Ultra precise temperature control with excellent visibility.

Model Name : VB-25G/40G


Performance

  • Temperature range from ambient +5°Cto 150°C.
  • Microprocessor PID control / Automatic tuning / Calibration.
  • Optimal temperature equilibrium achieved by a vane type stirrer with strong circulation power.

Convenience

  • Easy readout digital LED displays.
    (0.01°Cresolution at 0 to 99.9°C/ 0.1°C resolution at 100 to 150°C)
  • Dual wait on/off timer modes. (1 min. to 99 hr. 59 min.)
  • Convenient memory function of up to three frequently set temperature.
  • Clear visibility provided by double tempered safety glass windows in front and rear sides.
    (for operation from 10°C, use an optional cooling circulator)
  • Ø 51mm holes (for glass capillary viscometer tubes) and a Ø12.6 mm hole. (for a thermometer)
  • RS-232 interface for external control and data collection.

Safety

  • Isolated design of agitator, heater, and sensor by a baffle plate to minimize the turbulence in the bath fluid and also to protect users and samples against direct contact.
  • Complete safety protection system with warning alarms.
    - Low fluid level and dry-running, over-temperature, over-current.
  • Ideal for application requiring high visibility

  • Easy holding of U-shaped viscometer glass tubes (optional)
