The Newport 350B is a precision temperature controller engineered for thermal management across scientific and industrial applications. It maintains stable temperature setpoints through advanced PID and On/Off control algorithms while supporting multiple sensor types—thermocouples, RTDs, thermistors, and analog inputs. The unit delivers temperature stability to within ±0.01°C under optimal conditions and features programmable multi-step thermal cycling profiles for complex ramp/soak sequences.
