Uses:
with precise temperature and humidity control system, this equipment provides variety of environmental simulate conditions that industrial research and biological test need. It is used in medicine, textile and food production experiment, as well as in product stability, raw material, packing and lifetime test.
Characteristics:
1. Unique internal wind circulation, fan breeze circulation.
2. Intelligent PID temperature control system, high temperature control accuracy. Imported humidity sensor module.
3. The double door structure, with high quality glass easy to observe the samples, the outer door with magnetic strip, good sealing.
4. The upgraded humidifying system has the advantages of small particles, good humidity uniformity and low water consumption
