Performance

Temperature range.
- RW3-35 models from -35℃ to 150℃.
- RW3-25 models from -25℃ to 150℃.
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
Max. pressure (psi)	0.5	1.1	2.4	4.9	5.9
