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.

1) Technical data according to DIN 12876. (bath fluid : water at 70℃)

2) If you want to operate the unit below Amb. + 5℃, an optional cooling circulator is required.

The lowest temperature when using an optional cooling circulator is +10℃.

Viscometer tube holders

Specially designed to hold a two-opening viscometer glass tube and made of Bakelite, renowned for its high thermal endurance.

Cat. No.	Suitable for
AAA43501	VB-25G (need max. 5 holders)
AAA43501	VB-40G (need max. 8 holders)

Cooling circulators

The temperature range of viscometer heating baths can be lowered up to +10°C (+50°F) when used with an optional cooling circulator.
