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.
Monitor via mobile app anytime, anywhere with LC Connected (mobile monitoring system) connection. (when purchased LC GreenBox)

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)
