Special Temperature and Humidity Test Chamber with 90° and 45° Angle Rain Spray
In modern industries such as automotive, electronics, aerospace, and defense, products are expected to withstand extreme environmental conditions - from fluctuating temperatures and humidity levels to direct rain impact.
LIB's Special Temperature and Humidity Test Chamber with 90° and 45° Angle Rain Spray is an advanced and versatile testing solution that combines precise climate control with directional rain simulation to ensure products meet international reliability and durability standards.


【How Does LIB Ensure Accurate Testing of Climate Resistance and Water Ingress with a Single Chamber】
- Advanced Environmental Simulation Capabilities
LIB's test chamber is designed to simulate a wide range of environmental conditions with high accuracy and repeatability. The temperature control system allows testing between –70 °C to +150 °C, making it suitable for extreme cold and heat resistance evaluations. The humidity range of 20% to 98% RH ensures products can be tested under both dry and moisture-rich environments.
With fast heating and cooling rates (3 °C/min and 1 °C/min respectively), and temperature fluctuation within ±0.5 °C, the chamber ensures stable and precise control over every testing cycle. The humidity deviation is just ±2.5% RH, enabling accurate aging and performance tests in high-humidity environments.

- Unique Rain Spray Functionality at 90° and 45° Angles
What sets this special chamber apart is the integrated rain spray system. Designed to deliver controlled rain impact at both 90° and 45°angles, this system simulates real-world water exposure conditions such as rainfall, splash, and run-off on product surfaces.This high-precision sensor works with wet gauze to provide real-time, accurate monitoring of environmental conditions inside the chamber.
This capability is especially valuable for automotive components, outdoor electronics, and enclosures that must remain functional after exposure to driving rain or angled precipitation. The dual-angle spray ensures comprehensive water ingress testing, including scenarios that may affect seals and so on.

- Precision Sensors and Controller
At the heart of this chamber is a PT-100 Class A temperature and humidity sensor, boasting ±0.001 °C accuracy. This high-precision sensor works with wet gauze to provide real-time, accurate monitoring of environmental conditions inside the chamber.
An advanced controller supports PID programming, real-time data visualization, and up to 120 customizable programs, each with 100 steps. Multi-language support and remote monitoring via Ethernet make this system user-friendly and suitable for both R&D and quality assurance teams.
- Corrosion-Resistant and Durable Structure
The internal structure of the chamber is constructed using SUS304 stainless steel, providing excellent resistance against corrosion, temperature fluctuations, and humidity damage. The outer structure is built from 4mm A3 steel with a protective plastic coating, ensuring long-term durability even under continuous high-stress testing.

- Uniform Airflow and Eco-Friendly Water System
To maintain even environmental conditions, the chamber utilizes a centrifugal fan system that circulates hot or cold air uniformly throughout the test space. This prevents hot or cold zones and ensures every part of the test sample is subjected to the same conditions.
The integrated water purification system filters out impurities before they enter the humidity system, extending the life of sensors and internal piping while maintaining stable humidity levels. This can help the water saving and enhance the eco-friendly use of the water from the environment. It can also ensure the part of using the environment resources.
