Combined Pharmaceutical Stability Test Chamber — Multi-chamber Series
Product Features
- Combines stability and lighting tests to shorten testing time, save floor space and avoid equipment changes during testing;
- A special antibacterial stainless-steel chamber with rounded corners is easy to clean and convenient to use;
- New CFC-free design offers high efficiency and low energy consumption to promote energy savings;
- An LCD touchscreen controller displays all functions graphically and in text, with curves showing equipment operating status;
- Continuous operation: two imported hermetic compressors switch automatically to ensure prolonged continuous operation without faults;
- 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;
- Independent temperature, humidity and lighting control in each chamber shortens testing time and improves efficiency when researching and developing new drug stability;
Tiered Access Management
Programmable Touchscreen Controller (Refer to SDP/GSP Series)
- 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;
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;
3Q qualification and calibration services are available.
