Sample heating power supply HEAT3-PS

Power supply operated by touchscreen with dual mode heating (resistive and electron bombardment) and high efficiency.

The power supply can also be used for effusion cell evaporators. The unit is equipped with a PID temperature controller.
Ramp heating function control sample temperature to protect sample from damage. Sample overheating can also be protected by setting the voltage and current limits. The unit can be operated in auto mode (with temperature control) or manual mode (without temperature control).
