JeioTech – Viscosity Bath

The Jeio Tech Viscosity Bath (VB series) is a high-precision heating bath

Used for kinematic viscosity measurement, providing ultra-temperature control with excellent visibility.

This unit is supplied with an easy-to-read digital LED display, double tempered safety glass windows, and a baffle plate screen to decrease bath fluid turbulence.

Key Features

Performance • Temperature range from ambient +5°C to +150°C • Microprocessor PID control with temperature calibration, automatic tuning and automatic run • Optimal temperature equilibrium achieved by a vane type stirrer with strong circulation power Convenience • Easy readout digital LED displays (0.01°C resolution at 0 to +99.9°C / 0.1°C resolution at +100 to +150°C) • Dual wait on/off timer modes (1min to 99hr 59min) • Convenient memory function of up to three frequently set temperatures • Clear visibility provided by double tempered safety glass windows in front and rear sides

• Operations at below or slightly above ambient temperature allowed by stainless steel cooling coil (for operation from +10°C, use an optional cooling circulator) • Ø 51mm holes (for glass capillary viscometer tubes) and a Ø 12.6mm hole (for a thermometer) 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 and over-current • Keypad lock function prevents accidental changes
