2. Timer Function: Equipped with an OMRON timer, heating and vacuum extraction will stop upon completion, along with an alarm notification.
3. Thermocouple Type K;
4. Output voltage: 3-32V
5. The current controller is a PID + SSR solid-state relay.
6. Heating Method: Employing a three-sided radiant heat method; (left, right, and bottom sides)

10. Display Accuracy: 0.1℃
11. Inside box temperature deviation: ±5.0℃ (no vacuum, unloaded test)
Section 4: High-Temperature Vacuum Test Chamber System
1. Door sealing method: The machine door uses high-density silicone seal strips for sealing.
2. Vacuum Display Method: Vacuum gauge for vacuum level indication.
3. The vacuum control method is: automatic control. The vacuum pump stops when the vacuum reaches the set value, automatically replenishes vacuum when it falls below the upper limit, and cycles this process to maintain a constant vacuum state.
4. Pressure relief method: After the test, manually initiate the pressure relief function for pressure release; controlled by an electromagnetic valve.
5. Machine vacuum range: ≤1.0×10^5 to 1.0×10^1 (Pa), [i.e., 10 Pa]
6. Vacuum Pressure Leak Rate: 0.01 Pa/L per second
7. Vacuum Tube: Stainless steel vacuum corrugated tube used.
8. Vacuum Sensor: Equipped with KF16 vacuum resistance gauge tube.
9. Vacuum Setting Method: The vacuum level can be freely set as needed, such as for a vacuum level of (100Pa), the gauge is set to (1.0 E 2), and for a vacuum level of (10Pa), the gauge is set to (1.0 E 1), etc. It employs upper and lower limit controls for vacuum extraction and stoppage.
10. Vacuum Control Valve: Utilizes KF40 fitting high vacuum differential pressure valve with charging pressure.
11. Vacuum Pump Configuration: Dual-stage direct-connected oil pump used.
12. Vacuum Degree Display: Utilizes a resistance vacuum gauge to display the vacuum level, with the display in scientific notation format.
