Temperature Test Chamber

1. Temperature range: -70℃ to +150℃; Humidity range: 10% to 98%RH, meeting various environmental simulation test requirements.

2. Temperature fluctuation ≤ ±0.5℃, temperature uniformity ≤ 2℃, temperature deviation ±2℃, humidity deviation +2 to -3% (>75%RH) or ±5% (≤75%RH), ensuring accurate and reliable data.

3. Complies with the requirements of GB/T 2423.1 Low Temperature Test, GB/T 2423.2 High Temperature Test, GB/T 2423.3 Constant Damp Heat, GB/T 2423.4 Alternating Damp Heat, GJB 150.3 High Temperature Test, GJB 150.4 Low Temperature Test, and GJB 150.9 Damp Heat Test standards.

4. Integrated structure: the upper chamber is the working chamber, and the lower chamber is the refrigeration unit. The outer wall is made of cold-rolled steel plate with electrostatic powder coating, and the inner material is SUS304 stainless steel with a 100mm thick fiberglass insulation layer, providing excellent insulation.

5. A 400×500mm frost-proof glass observation window is provided on the main door for easy observation of the sample status.

6. There is a Φ100mm lead-in hole on each side with a soft plug for easy insertion of test cables.

7. The equipment is equipped with casters for easy movement and positioning of the test chamber.

8. It adopts a 7-inch color LCD touch screen control panel, which can switch between Chinese and English, supports fixed-value operation and program operation, and has a user program capacity of up to 90 programs, each with a maximum of 99 segments.

9. It has a USB data interface to store operating parameters such as test time, target value, and measured value, and supports hot-swapping and historical data download.

10. It adopts a cascade compression refrigeration method and uses environmentally friendly refrigerants R404a and R23. No heating balancing is required when maintaining a constant temperature at any low temperature point, reducing operating power by up to 60% and saving operating costs.

11. It is equipped with multiple safety devices, including over-temperature protection for the working chamber, over-heat protection for the fan, over-pressure, over-current, and over-heat protection for the compressor, exhaust temperature protection, phase loss protection for the power supply, short-circuit protection for the heater, water shortage protection for the humidification system, and grounding protection for the outer casing.

Hoson Company's registered capital: 18.27 million yuan

Q1: What are the payment methods?

A1: We support bank wire transfer. Generally, we use a deposit payment followed by the balance payment before shipment. For long-term clients, we can apply for more flexible payment terms..

Q2: How long is the delivery time of temperature test chamber?

A2: Standard models generally take 20 working days, depending on the production schedule. For non-standard customized products, the delivery time will be confirmed separately based on the complexity of the customization.

Q3: Do you support customization? What aspects can be customized?

A3: We support non-standard customization. We can customize the chamber size, temperature range, humidity range, number of shelves and load-bearing requirements, number and location of test lead holes, observation window size, and add remote data monitoring functions, etc. We can provide 3D design drawings for customer review within 10 days of contract signing.

Q4: What are the installation requirements?

A4: The installation requires adequate access space, a ground load-bearing capacity of at least 350 kg/m², and sufficient maintenance space around the equipment. The ambient temperature should be between 5℃ and 35℃, and the humidity ≤85%RH, with no strong electromagnetic radiation sources nearby. It is recommended to use pure water for humidification, the equipment can automatically replenish water.

Q5: How do you guarantee product quality?

A5: We possess our own core processing equipment, including laser cutting machines, bending machines, and spray painting lines, controlling quality from the source. We utilize CATIA 3D design to develop scientific process specifications. Our refrigeration system employs oxygen-free protected welding, and the pipelines undergo 24-hour pressure testing. We are ISO9001 quality system certified, ensuring comprehensive quality control from raw materials to finished products. We welcome customers to conduct video factory visits to assess our production capacity and management level.

Q6: How long is the after-sales service for the equipment?

A6: The entire machine has a 12-month warranty, with free repair for malfunctions caused by product quality issues. Beyond the warranty period, we provide long-term technical consultation services, free product manuals and maintenance advice, and replacement parts will be charged at our discretion.
