Pressure Control	The pressure control system monitors and controls the chamber pressure. The pressure setpoint and holding time are user-defined (default 11.6kpa for 6 hrs).  4.3" Touch-screen PLC panel to control & display pressure and running time automatically. Optional ( at extra cost ) Can add pressure setting programmable function up to 9 segments according to the request. Can add heating programmable function up to temperature of 250°C
Accessories	One 156 L/m Double Stage Rotary Vane Vacuum Pump with Exhaust Filter, Bellows & KF-D25 Inlet, and vacuum pipe are built in the bottom of the box for immediate use. 4 mobile wheels are installed for easy moving You can order NIST traceable digital gauge to calibrate vacuum chamber pressure at extra cost ( click Pic below right to order
Compliance	CE Certified The oven is ready to pass TUV(UL61010) or CSA certification at extra cost.
Attention Note	Please be aware that the welding joints inside the chamber are ground in order to smooth out the surface, however, they are not mirror-polished.
