Application Overview
Scientifically establishes long-term stable temperature, humidity and lighting conditions for evaluating the shelf life of pharmaceutical batches. It is suitable for accelerated, long-term and high-humidity tests of medicines and new drugs in pharmaceutical companies. It provides a reliable solution for bulk pharmaceutical storage and stability testing, facilitating long-term moisture-resistance cycling tests for large batches.
Product Features
- An imported color LCD touchscreen switches freely between Chinese and English, provides 100 programs for users to set/save, and displays operating data;
- TMHM balanced temperature and humidity regulation provides stable operation and precise, safe, reliable control;
- An air-duct circulation system ensures uniform temperature and humidity distribution inside the test room;
- Safety devices make operation safer and more reliable;
- Data recording and fault-diagnosis display: if the test chamber develops a fault, the dynamic display shows fault information. A printer or 485 communication interface can be connected. Computer software records temperature, humidity and time curves in real time, supporting storage and playback of experimental data;
- An anti-entrapment device allows personnel to enter and exit the test room safely;

Optional Accessories
Wired Monitoring Alarm System
- A wired alarm system continuously monitors instrument operation. When no personnel are present at the test site, the equipment can be monitored effectively from another room or department, with fault alarms.
Automatic Illuminance Monitoring and Control
- Overcomes the inability of existing domestically produced stability chambers to monitor and control illuminance. An optical sensor provides monitoring and stepless adjustment, reducing illuminance decay and test errors caused by lamp aging.
Wireless Alarm System (SMS Alarm System)
- If the equipment user is away when a fault occurs, the system promptly collects fault signals and sends an SMS to the designated recipient’s mobile phone. This supports prompt fault correction and resumption of testing, preventing losses.
UV Sterilization System
- The UV sterilization lamp on the rear chamber wall periodically disinfects the interior, effectively killing airborne bacteria in the circulating air and water vapor from the humidification tray, preventing contamination during pharmaceutical testing.
- 3-inch LED display with standard USB2.0 interface;
- Supports data transfer to a USB flash drive;
- Facilitates saving data needed for GMP certification.
- Touchscreen and MMI human-machine interface for simple, convenient operation;
- Standard RS232C/RS485 communication protocols; PC software can be configured;
- Meets IP-65 dustproof and waterproof requirements;
- Large-capacity data storage with a standard 2GB SD memory card allows users to download historical records freely;
- Supports switching between Chinese, English, Japanese and Korean.
