информация о продукте

 1. Airduct structure   It applies circular airflow design concept and forced convection simulated air circulation principle. The large power air circulating blades designed specially can produce higher air flow rate and guarantee high even and stable inner bag temperature and humidity.

2. Electronic humidity sensor It is used for absolute precise humidity measurement. The humidifying and dehumidifying system is controlled electronically. ROTRONIC electronic humidity sensor can guarantee the reliability of humidity inspection even if the samples are changed frequently. The senor does not require maintenance.

3. Innovative refrigerating system    International famous brand refrigerant compressor and Germany EBM condenser applying 134a refrigerant and featuring fluorine free, environmental protection, precision and high efficiency are applied.

4. Test hole      One test hole with the diameter of 45mm made with special mould is arranged on the left and right of the incubator respectively for observation. Internal silica gel soft plugs are provided to make sure the temperature and humidity inside the incubator are not affected during the test.

5. Easy for maintenance  It is easy to maintain and clean condenser to improve the refrigerating performance and save energy.

6. RS232 interface It is a special interface for PC. One software CD (suitable for simplified Chinese WINDOWS2000 or simplified Chinese WINDOWS XP operating system) is attached. Test program is written, monitored and saved with special PC software. Test data is directly displayed and printed with special PC software.

7. Ponded water inside inner bag can be discharged easily  The inner bag applies side, high, middle and low structures to discharge water easily and keep the incubator clean.

 Application scope: It is mainly applied for long term storage test of drugs, food quality test, environmental test of resin material, auto parts and electrical & electronic appliances, water body analysis, BOD test, bacteria culture, microorganism culture, vaccine storage etc.

Features: 

◆ The incubator is made with imported NC machine tool and laser processing technology. The outside incubator body applies high quality cold rolling plate, which is strongly resistant to rusting. The inner bag applies SUS304 stainless plate. 

◆ The incubator bottom truckle is imported from Japan. Its direction is adjustable and it can be locked. The outside incubator body is sprayed with American Dupont powder.

◆ One test hole with the diameter of 45mm made with special mould is arranged on the left and right of the incubator respectively for observation. Two silica gel soft plugs are provided inside.

◆ The heat insulating material of incubator applies Germany Bayer freon-free polyurethane one-time foaming technology to improve the insulating property and reduce energy consumption. It can save over 30% energy in comparison with similar products. The overall strength of incubator is good. 

◆ Rational airduct structure; balance type control method; imported special electric motor and blade are applied to make temperature and humidity distribution evener and greatly improve test precision and evenness of temperature and humidity.

◆ The defrosted water inside incubator will vaporize through compressor.

◆ International famous brand refrigerant compressor and Germany EBM condenser applying 134a refrigerant and featuring fluorine free, environmental protection are applied and conform to the world trends.

◆ Programmed temperature and humidity control; micro-computer fuzzy control PID control; temperature priority and time priority; optional for the user. Intelligent programmed mode is applied. The control part applies high brightness super large LCD and fuzzy PID control method to be more humanized.

◆ Temperature sensor PT100 applies Honeywell product. The humidity sensor applies Swiss Rotronic capacitive sensor.

◆ Over-temperature protection, creepage protection, door open alarm, current failure alarm and sensor alarm functions are provided to improve the safety. Meanwhile, automatic start, stop, timed operation, clock display and self recover after energization are provided.

◆ Automatic defrosting and manual defrosting functions are provided for long term test to solve the problem of temperature and humidity drifting.
