Intelligent program control

10 programs available for temperature ramp up and dwell control.
10 steps per a program and 99 hours 59 minutes per a step.
Stored programs are easily linkable.
Programs can be repeated up to 99 cycles.
Pre-heating and heating time are settable before program starts.

Performance

Temperature range.
- RW3-35P models from -35°C to 150°C.
- RW3-25P models from -25°C to 150°C.
Microprocessor PID control.
Three point temperature calibration / Automatic tuning / Automatic run.
Suitable for both internal and external bath environments due to reduced turbulence by using five-speed adjustable pump and built-in cooling coil.
(1 to 3 steps of the pump for internal circulation and 4 to 5 steps for external circulation)

Pump Step	1	2	3	4	5

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.
Temperature warning Indicator simply shows inner reservoir’s temperature by three different colors.
Complete safety protection system with warning alarms.
- Low fluid level and dry-running, over-temperature, over-current.
Keypad lock function prevents accidental changes during operation.
Splash-proof keypad.
