Scientifically establishes long-term stable temperature, humidity and lighting conditions for drug shelf-life evaluation. Suitable for accelerated, long-term, high-humidity and intense-light exposure tests of medicines and new drugs in pharmaceutical companies, it provides a reliable solution for pharmaceutical stability testing.
Product Features
- New CFC-free design offers high efficiency and low energy consumption to promote energy savings;
- An antibacterial stainless-steel chamber with rounded corners is easy to clean and convenient to use;
- Microcomputer servo controller with digital temperature and humidity display (SD/GSD models have this function);
- LCD touchscreen controller displays all functions graphically and in text, with curves showing equipment operating status (SDP/GSP models have this function);
- Continuous operation: two imported hermetic compressor units switch automatically to ensure continuous operation;
- Continuous operation requires no defrosting, avoiding chamber temperature and humidity fluctuations caused by defrosting during use;
- An imported humidity sensor avoids frequent wick replacement associated with conventional wet- and dry-bulb sensors;
- GSD/GSP series provides stepless illuminance adjustment;
Safety Functions
- Air circulation and heating stop automatically when the door opens to prevent temperature overshoot;
- Automatic circulating fan speed control prevents sample evaporation caused by excessive airflow;
- Password-protected screen locking prevents incorrect operation by non-laboratory personnel;
- An independent temperature-limit alarm system provides audible and visual warnings;
- Temperature-deviation alarms; compressor overheating, overload and overpressure protection; water-shortage protection;
- Wired monitoring alarm system (SDP/GSP series has this function)
3Q qualification and calibration services are available.
Tiered Access Management
- Multiple individual accounts can be assigned according to equipment-management requirements, with three controller access levels: administrator, operator and guest. The touchscreen supports Chinese and English input, allowing users to log in under their actual names. Detailed user-operation logs can also be queried for equipment operation, maintenance and audit trails;
