The DHT® Pharmaceutical Stability Test Chamber is designed to simulate the storage environment of pharmaceutical products under varying temperature and humidity conditions, in order to assess their stability and shelf life. This equipment is widely used in the pharmaceutical, biotechnology, food industries, electronics, and life sciences for in-depth research.
Precise Temperature and Humidity Control The chamber is equipped with a high-precision temperature and humidity control system, with a typical temperature range from 0°C to 65°C and humidity range from 20% RH to 95% RH, ensuring the stability of the test environment.
Reliable Cooling System Featuring dual fully enclosed, high-temperature resistant compressor units, the system ensures long-term stable operation of the chamber and supports both constant and programmable operating modes.
Intelligent User Interface The chamber is equipped with an integrated touchscreen controller for temperature and humidity, supporting both English and Chinese language options. It records historical data and includes interfaces such as RS232, RS485, and USB for convenient data transmission and monitoring.
High-Quality Materials The interior is made of stainless steel (SUS304), and the exterior is constructed with corrosion-resistant, easy-to-clean spray-painted steel plates, ensuring durability and hygiene.
Adjustable Shelving Design The built-in shelves are adjustable, facilitating easy sample access and internal cleaning.
Light Simulation Function (Optional) Certain models are equipped with a light system that simulates the effects of different light conditions on pharmaceutical stability.
