When materials, devices, or products need to be tested under controlled temperature and humidity, a Constant Temperature Humidity Climatic Chamber becomes essential. These chambers replicate real-world conditions, allowing engineers and QA specialists to evaluate performance, durability, and safety in a precise, repeatable manner.
Modern research, automotive, electronics, and pharmaceutical labs demand more than simple temperature control-they require stability, accuracy, and flexibility. Constant Temperature Humidity Climatic Chambers deliver this by maintaining exact temperature and humidity cycles, ensuring test results are reliable and comparable.
LIB Constant Temperature Humidity Climatic Chamber can simulate environments from extreme cold (–70 °C) to intense heat (+150 °C) while controlling relative humidity from 20 % to 98 % RH. It provides rapid thermal transitions, long-term holds, and accurate sensor feedback, making it suitable for everything from short-term stress tests to 1000-hour aging trials.
1. Introduction of Constant Temperature Humidity Climatic Chamber
Why Use a Climatic Chamber?
Climatic chambers are designed to reproduce the environmental conditions products face in the real world. By controlling temperature and humidity precisely, researchers can evaluate how materials expand, contract, or degrade, ensuring that products meet safety and reliability standards.
How a Climatic Chamber Works
Inside the chamber, advanced PT100 Class A temperature probes and wet-bulb humidity sensors monitor conditions with ±0.001 °C and ±2.5 % RH accuracy. Air is circulated by multi-directional centrifugal fans to keep the internal environment uniform, eliminating hot or cold spots for every sample, from small PCBs to large automotive assemblies.

Precision & Repeatability: Temperature ranges from –70 °C to +150 °C with ±0.5 °C stability; humidity spans 20 % to 98 % RH with ±2.5 % RH consistency. Rapid thermal ramps of 3 °C/min heating and 1 °C/min cooling accelerate test cycles without sacrificing stability.
Durability & Maintenance: Interiors use SUS304 stainless steel; exteriors are powder-coated A3 steel. Observation windows, internal LED lighting, and lockable leveling castors make the chamber user-friendly and low-maintenance. Silicone seals prevent leaks, and built-in safety interlocks guard against over-temperature, low water, door-open, or power-failure events.
Operational Efficiency: Up to 120 programmable test protocols with 100 steps each; real-time monitoring, remote connection via PC Link, or optional Wi-Fi for $2,063. Closed-loop water-recovery system reduces water consumption by up to 70 %, and energy-smart insulation cuts electricity by 20–30 %. Noise stays below 65 dB(A).
Sustainability & Adaptability: Chambers are energy-efficient, quiet, and designed for continuous operation. Adjustable racks, cable ports, and sliding/hanging fixtures ensure each test matches specific material or product requirements.

4. FAQs on Constant Temperature Humidity Climatic Chamber
1. Can Temperature Humidity Test Chamber power connection cable come with a plug instead of bare wires?
We recommend preparing your own plug. Leaving the chamber without a plug avoids wiring errors in the lab and ensures safer and more reliable operation.
2. Will modifying Temperature Humidity Test Chamber standard design or changing chamber size increase costs?
Yes. Non-standard custom designs usually incur extra costs. The exact amount depends on modification complexity and material usage, and we provide transparent quotes.
3. For fast temperature change rate, what is Temperature Humidity Test Chamber maximum possible? Can it reach 20 °C/min?
The standard rate is 5–10 °C/min, but we can customize to achieve 20 °C/min or higher to meet your special applications.
4. What is Temperature Humidity Test Chamber dew point temperature?
Temperature Humidity Test Chamber series mainly tests relative humidity (RH) and does not directly measure dew point temperature.
5. Does Temperature Humidity Test Chamber have remote connection capability?
Standard chambers include PC Link connection. For wireless remote control, optional Wi-Fi is available for $2,063.
