High-low temperature humidity chamber - Professional Environmental Testing Equipment
As a professional manufacturer of environmental testing equipment, we focus on providing high-quality high and low temperature alternating test chambers for global customers. Our products are widely used in electronics, automotive, aerospace, battery, PCB, and other industries, helping you conduct reliable temperature cycling tests to verify the stability and durability of products under extreme temperature conditions.
Product Overview
Our high and low temperature alternating test chamber is a specialized environmental testing device designed to simulate the alternating changes of high and low temperature environments in nature. It can accurately control the temperature range, cycling time, and temperature change rate, enabling your products to undergo rigorous temperature stress tests before leaving the factory. Unlike temperature-humidity cycling chambers, this equipment only controls temperature without humidity regulation, which is more cost-effective and suitable for scenarios that only require temperature cycle testing.

Core Advantages
- Precise Temperature Control: Equipped with imported temperature controller and high-sensitivity temperature sensor, the temperature control accuracy can reach ±0.5℃, and the temperature fluctuation is ≤±1℃, ensuring the accuracy and repeatability of test data.
- Stable Performance: Adopts high-quality refrigeration compressor and heating system, with fast cooling and heating speed, stable operation, low noise, and long service life. It can continuously work for 24 hours without failure, meeting long-term test needs.
- Flexible Programming: Supports programmable temperature cycling, allowing you to set multiple temperature points, holding time, and temperature change rates (optional 1-15℃/min rapid temperature change), which can be customized according to different test standards and product requirements.
- Humanized Design: The chamber is made of 304 stainless steel, corrosion-resistant and easy to clean; the touch screen operation interface is simple and intuitive, with English display, easy to operate for global users; equipped with over-temperature, over-pressure, and power failure protection functions to ensure the safety of equipment and test samples.
- Cost-Effective Solution: Compared with temperature-humidity alternating test chambers, it has no humidification and dehumidification system, lower production cost, and more favorable price, which can meet your basic temperature cycle test needs at a lower cost.
Reference Standards
Our high and low temperature alternating test chambers fully comply with international and domestic mainstream test standards, ensuring that your test results are authoritative and recognized globally:
- IEC 60068-2-1 (Low Temperature Test)
- IEC 60068-2-2 (High Temperature Test)
- IEC 60068-2-14 (Temperature Change/Temperature Cycling Test)
Key Difference: High and Low Temperature Alternating vs. Temperature-Humidity Alternating Test Chamber
Many customers confuse these two types of equipment. Here is a clear comparison to help you choose the right product:
| High and Low Temperature Alternating Test Chamber | Temperature-Humidity Alternating Test Chamber |
|---|
| | Temperature + Humidity (20%-98%RH) |
| No humidification/dehumidification system | With humidification, dehumidification and condensation control systems |
| More cost-effective (lower) | Higher (usually 20%-40% more expensive) |
| Temperature cycling, high-low temperature storage, temperature shock | Temperature-humidity cycling, damp heat aging, condensation test |
| IEC 60068-2-1, -2, -14; GB/T 2423.1, 2423.2 | IEC 60068-2-78; GB/T 2423.3, 2423.4 |
