10. Equipped with brake casters for easy movement.

Section 3: High-Temperature Test Chamber Temperature Control System

1. The temperature controller is a digital display instrument with single-point temperature control, capable of automatic calculation, displaying PV/SV simultaneously, and setting via buttons.

2. Timer Function: Equipped with an Omron timer, heating and vacuum extraction will stop automatically upon completion, with an alarm to notify.

3. Thermally sensitive wire type K;

4. Output voltage: 3-32V

5. The current controller is: PID + SSR solid-state relay.

6. Heating Method: Utilizes three-sided radiant heating (left, right, and bottom sides).

7. Heating materials include: stainless steel high-temperature heating tubes.

8. Temperature Range: room temperature +30℃ to 250℃ (adjustable and controllable within this range)

9. Control Accuracy: ±0.5℃

10. Display Accuracy: 0.1℃

11. Internal Temperature Deviation: ±5.0℃ (No vacuum, unloaded test)

Section 4: High-Temperature Test Chamber Vacuum System

1. Door Sealing Method: The machine door is sealed with a high-density silicone seal strip.

2. Vacuum Display Method: Vacuum gauge for vacuum level indication.

3. The vacuum control method is: automatic control. The vacuum pump stops working 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 testing, 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 Preservation Pressure Leak Rate: 0.01 Pa/L per second.

7. Vacuum Tube: Made with stainless steel vacuum corrugated tube.

8. Vacuum Sensor: Utilizes KF16 vacuum resistance gauge tube.

9. Vacuum Setting Method: The vacuum level can be freely set according to requirements. For instance, a vacuum level of (100Pa) is set at gauge (1.0 E 2), and a vacuum level of (10Pa) at gauge (1.0 E 1), etc. The vacuum and stoppage of vacuum extraction are controlled using upper and lower limits.

10. Vacuum Control Valve: Equipped with KF40 flange high vacuum differential pressure valve with filling pressure.

11. Vacuum Pump Configuration: Dual-stage direct-connected oil pump used.

12. Vacuum Level Display: Utilizes a resistance vacuum gauge to display the vacuum level, with the display format in scientific notation.

V. Nitrogen Filling Device for High-Temperature Test Chambers
