High Low temperature & humidity environmental test chambers
Temperature & humidty environmental test chamber is used to test and store a wide range of products in specific temperature and/or humidity conditions. Applications include, but are not limited to, shelf life testing, stability testing, expiration date testing, accelerated aging and other testing for pharmaceutical, packaging, life science, personal care, medical, bio-medical storage, research, and more.
Features
1. The content can be enlarged or narrowed according to user's environmental requirement.
2. Combined board, convenient to assemble and disassemble, simple structure.
3. Use pollution-free freezing medium R404, R23.
4. Capacious and brightly observation window with high light indoor explosion-proof, whitch allowed users to observe all indoor at any time.
5. Omni-directional safety protection device and power-off memory, ensure the safety of machine itself and users.
6. Winds blow out of the ceiling, whitch can reduce the influence of the wind indoor to the sample, and can also meet the demand of low wind speed and high degree of uniformity. The machine can contact to the computer, recorder(optional).

High temperature storage condition test:
Put the test sample into the temperature chamber, let the temperature in the chamber rise (1°C/min) to 105°C or 85°C (water-cooled model 105°C, air-cooled to 85°C), and keep for 48h.
Lower the temperature (1°C/min) to normal atmospheric conditions, and recover for 1 hour under these conditions. The cooling time in the chamber is not included in the recovery time.

Low temperature storage condition test:
Put the test sample into the chamber, make the temperature in the chamber drop to -40°C, keep it for 24h, and the temperature rise and fall rate is 1°C/min. Raise the temperature to normal atmospheric conditions, and recover under these conditions for 1 hour. The heating time in the box is not included in the recovery time.
