Q1: How to choose between different models?
A: Models without "A" suffix (e.g., GPL-250) are basic lighting incubators suitable for experiments requiring only lighting and temperature control (e.g., plant photoperiod studies). Models with "A" suffix (e.g., GPL-250A) include humidity control for simulating full climatic environments (e.g., pest cultivation, seed germination). Choose based on whether your experiment requires precise humidity control.
Q2: What are the accuracy and uniformity of temperature and humidity control?
A: Temperature uniformity: ±2°C, fluctuation: ±0.2°C (balanced operation). Humidity deviation: ±3%RH (balanced operation). Performance data is measured under no-load conditions at 20°C ambient temperature and 50%RH ambient humidity. Actual parameters may vary with loading and environmental fluctuations.
Q3: Is light intensity adjustable? What are the differences between models?
A: All models feature continuously adjustable light intensity. GPL-450 offers up to 25,000 LX; GPL-850/1000 offer 20,000 LX; smaller models provide 12,000 LX. LED cold light sources reduce heat and extend lifespan. Overhead lighting mode is available as an option for special requirements.
Q4: Can it simulate day-night cycles and complex climate conditions?
A: Yes, it supports multi-segment programming (up to 30 programs, 1-99 hours per segment). Temperature, humidity, light intensity, and time can be set separately to simulate day-night variations, photoperiod cycles, and other complex experimental processes. Programs are saved automatically during power outages and resume when power is restored.
Q5: How is humidity control achieved?
A: Using proprietary intelligent humidification/dehumidification technology with built-in water tank and sensor feedback. Includes low-water alarm. For long-term high-humidity operation, a door heating function (optional) reduces condensation on the glass door.
Q6: What safety features are included?
A: Four-layer protection: 1) Independent over-temperature alarm 2) Fault self-diagnosis (displayed on LCD) 3) Built-in leakage protection switch 4) Optional wireless SMS alarm system (sends fault alerts to designated phones).
Q7: What should I know about cleaning and maintenance?
A: The chamber features mirror stainless steel with rounded corners for easy cleaning. Shelves are made of 304 stainless steel and can be disassembled without tools. The cooling system has a dust filter that requires regular cleaning. We recommend quarterly internal cleaning and annual checks of seals and sensors.
Q8: What data logging and communication options are available?
A: Optional: 1) RS485/USB interface with PC software for real-time data recording 2) Printer system (GMP-compliant) 3) True color touchscreen control system. Recommended for long-term experiments or projects with compliance requirements.
Q9: Can CO2 concentration be controlled?
A: Available as an optional upgrade using an imported infrared CO2 sensor. Suitable for plant photosynthesis studies or specialized microbial cultures requiring precise CO2 control. Standard models do not include this function.
Q10: What are the dimensions and power requirements?
A: All models require AC220V/50-60Hz power. The largest model (GPL-1000A) external dimensions: 1410×890×1930mm. Ensure sufficient space (recommended >30cm clearance on all sides for ventilation). Unlimited continuous operation, but ambient temperature must be maintained between 5-35°C.
