**YANSHUO Bench‑Top Constant Temperature and Humidity Test Chamber**
**【Scope of Application】**
The programmable constant temperature and humidity test chamber (also known as a programmable alternating temperature and humidity test chamber) is
used to test the performance of materials under various environmental conditions and to evaluate the heat resistance, cold resistance, dry resistance, and humidity
resistance of various materials. It is suitable for quality inspection and research in scientific research, medical, aerospace, educational institutions, and other fields.
**【Product Features】**
- Fully imported stainless steel housing or anti‑rust steel plate (powder‑coated) — attractive and elegant appearance.
- Imported refrigeration unit; all key components are international brands; the entire system is equipped with multiple protection devices to enhance operational reliability.
- Ingenious air duct design ensures minimal temperature and humidity deviation, high uniformity, and includes an anti‑condensation function.
- The door is equipped with an illuminated observation window for convenient viewing of specimen test conditions.
- The system is simple to operate, easy to install, and convenient to maintain.
