Altitude chamber / Vacuum low-pressure testing machine

This vacuum low-pressure (high-altitude) test chamber G-1029 simulates negative pressure environments to evaluate the performance and reliability of products under vacuum and high-altitude conditions. It is designed for precise control, high vacuum accuracy, and stable operation, suitable for a wide range of materials and electronic components.

Application

(1) Testing automotive electronic components under high-altitude and low-pressure conditions.

(2) Evaluating aerospace and aviation components subjected to vacuum or near-vacuum environments.

(3) Reliability testing of electrical and mechanical devices for high-altitude operations.

(4) Testing sensors, connectors, and electronic modules in automotive, aviation, and defense industries.

(5) Environmental testing of consumer electronics exposed to low-pressure conditions.

(6) Material durability and insulation testing under negative pressure.

Standards

(1) ISO 16750-2: Road vehicles – Environmental conditions and testing for electrical and electronic equipment.

(2) GB/T 28046.2: Environmental testing for automotive electrical/electronic devices – Part 2: Low-pressure test.

(3) VW 80000: Volkswagen Group environmental testing standard.

(4) GM 3172: General Motors environmental testing standard.

(5) Automotive OEM-specific standards (optional based on customer requirements).

Features

(1) High vacuum tightness using high-density silicone rubber seals.

(2) Built-in digital vacuum gauge for accurate relative vacuum display.

(3) Automatic vacuum control: cycles pump operation to maintain set vacuum level.

(4) Manual venting for safe sample removal after testing.

(5) Robust 304# stainless steel inner chamber with reinforced structure to prevent deformation.

(6) Outer cabinet made of powder-coated cold-rolled steel for durability.

(7) High thermal insulation with rock wool filling.

(8) Integrated viewing window for real-time observation of test samples.

(9) Compact integrated unit design for ease of installation and operation.

Parameters

Accessories

(1) Mesh shelf / panel.

(2) Silicone rubber seal spare set.

(3) User manual and maintenance guide.

(4) Power cable.

(5) Vacuum pump connection kit.

Test Procedures

(1) Place the test sample inside the chamber on the mesh shelf.

(2) Close the chamber door and ensure the silicone seal is properly seated.

(3) Set the desired vacuum level on the digital gauge.

(4) Start the vacuum pump; the system automatically reaches and maintains the set vacuum.

(5) If vacuum hold is required, enable the timer function.

(6) Monitor the sample through the viewing window during testing.

(7) After the test, manually release the vacuum before opening the chamber.

(8) Remove the test sample safely.

Maintenance Information

(1) Regularly check silicone seals for wear and replace if necessary.

(2) Clean the inner chamber with a soft cloth to remove dust and debris.

(3) Inspect the vacuum pump and connections for leaks before each test.

(4) Verify digital vacuum gauge calibration periodically.

(5) Ensure the chamber door closes properly to maintain vacuum tightness.

(6) Check power supply and circuit protection components regularly.
