Following the trend of world environmental protection, fluorine-free will be an inevitable trend in the development of refrigeration equipment in our country. Derek instruments are one step faster with a new fluorine-free design, so that you will always be in the forefront of a healthy life. International brand compressors and circulating fans, with high efficiency and low energy consumption, not only promote energy conservation, but also have a long service life, which can reduce noise to a lower limit. Compared with traditional low-temperature equipment, the cooling time can be saved by more than 40%. Use overview: It is widely used in microbial tissue cell culture, seed germination, seedling experiment, plant cultivation, insect and small animal feeding, etc. It can accurately simulate different environmental and climatic conditions. Features: l The microcomputer program controls the temperature, humidity, and illuminance, which can simulate the temperature and humidity changes during the day and night, and you can also choose a sufficient and stable light source for the growth environment. l 30 sections of programs can be set, and the time range of each section is 1-99 hours (optional). l International brand compressors ensure long-term continuous operation of the test equipment, environmentally friendly refrigerant (R134a), high efficiency, low energy consumption, and promote energy saving. l Mirror stainless steel liner is adopted, with four corners and semi-circular arc transition, and the partition bracket can be freely installed and unloaded, which is convenient for cleaning in the box. l Equipped with an independent temperature limit alarm system, which automatically interrupts when the temperature exceeds the limit, ensuring the safe operation of the experiment and no accidents. (Optional) l It can be equipped with RS485 interface and computer connection, through the computer to monitor the experiment process or record the experiment data synchronously. (Optional) l Can be equipped with: with CO2 air inlet (promoting plant growth) and CO2 controller (imported infrared CO2 sensor) Technical Parameter:
