1. Operational Efficiency: The heat cold and humidity test climatic chamber is equipped with a PID touchscreen controller supporting up to 120 programs with 100 steps each, allowing precise, automated testing. Remote monitoring via Ethernet or USB enables real-time data logging and one-click report export, saving time and reducing errors. With these features, operators can easily run complex test cycles efficiently while maintaining full control over test parameters.
2. Durability and Safety: The heat cold and humidity test climatic chamber interior is made of SUS304 stainless steel, resisting corrosion and maintaining structural integrity under high humidity. The exterior uses 4 mm A3 steel with powder coating, providing industrial-grade durability. Comprehensive safety systems—including leakage current protection, grounding, phase monitoring, and over-temperature shutdown—ensure both operator and equipment safety. These robust materials and protective systems guarantee long-term reliability even in demanding testing environments.
3. Air Circulation System: The Heat Cold and Humidity Test Climatic Chamber uses forward and reverse air circulation to distribute conditioned air evenly throughout the chamber. The circulation fan reduces temperature and humidity gradients, maintaining stable and uniform test conditions. This design improves test consistency and repeatability.
4. Test Precision and Repeatability: The humidity test chamber guarantees temperature stability within ±0.5 °C and a maximum deviation of ±2 °C. Humidity can be maintained between 20 % and 98 % RH with ±2.5 % accuracy. Fast ramp rates allow heating at 3 °C/min and cooling at 1 °C/min, customizable up to 20 °C/min. High-accuracy PT100 Class A sensors with ±0.001 °C resolution ensure every test is precise and repeatable. These features provide reliable and reproducible results for demanding laboratory and production testing. A cable hole is available for power and signal cables, so you can run powered or live samples during testing.

Turn on the main power and check that all connections are secure.
Set the required temperature, humidity, and ramp rates on the touchscreen controller.
Load samples evenly and keep them away from the chamber walls.
Monitor temperature and humidity throughout the test to make sure they stay within the programmed limits.
After each cycle, clean the chamber interior and wipe up any spills.
Carry out regular checks and handle the chamber properly to keep it performing well, extend its service life, and protect operators.
Q1: How is the heat cold and humidity test climatic chamber caLIBrated?
A: Factory caLIBration starts after assembly and includes temperature and humidity caLIBration. Nine temperature probes are placed inside to cover key points. Average readings are compared to standards, and hardware adjustments are made to ensure uniform temperature. Humidity is caLIBrated using the dry/wet bulb method, with hardware adjustments to reach standard values, ensuring accurate and reproducible testing.
Q2: What refrigerant is used in Europe? According to the latest European refrigerant regulations, can CO₂ refrigerant be used?
A: According to the European refrigerant regulations effective from January 1, 2024, the refrigerant used in temperature and humidity test chamber must have a GWP (Global Warming Potential) of 150 or lower. The refrigerant used in LIB Temperature Humidity Test Chambers fully meets this requirement, ensuring environmental friendliness and regulatory compliance. CO₂ refrigerant belongs to a different system technology and cannot be directly used to replace the current refrigerant in our equipment.
