I. Product Introduction
The superposed constant temperature incubator has an accurate temperature and humidity control system. It provides various simulated environmental conditions required for industrial research and biotechnological testing, and is widely used in scientific research, educational institutions, and production departments such as environmental protection, health and epidemic prevention, drug inspection, agriculture and livestock, and aquatic products. It is used for water body analysis and BOD determination, cultivation and preservation of bacteria, molds, and microorganisms, plant cultivation, breeding experiments, aseptic tests such as drug, textile, and food processing, stability inspection, and testing of raw material properties, product packaging, and product lifespan of industrial products.
2. Product Features
Superimposed constant temperature and humidity incubator
The streamlined and luxurious overall machine shape is full of aesthetic design concepts. The box body is electrostatically sprayed, and it has a double - door structure.
It is made by argon arc welding of mirror - surface stainless steel. The outer box is made of high - quality steel plate, with a beautiful and novel shape. The mirror - surface stainless - steel inner lining ensures that the instrument will never rust.
The LCD large - screen digital display shows all set parameters and measured parameters.
The high - performance constant - temperature function prevents the evaporation and drying of samples.
It has a built - in lighting system and an ultraviolet germicidal lamp.
The compressor is automatically controlled. The temperature control range is not affected by room temperature. It can be arbitrarily controlled from 4 to 60 degrees, and the compressor can defrost automatically (many brand devices do not have the automatic defrosting function: if defrosting is not carried out, the frost will accumulate thicker and thicker, and finally the fin evaporator will be covered with frost and block the air duct, resulting in the decline of the refrigeration effect due to the inability of cold air to circulate).
It is equipped with a humidifier. The humidifier has a humidity adjustment knob, and the humidity is automatically controlled by the controller.
A new type of synthetic silicon sealing strip is used, which can operate at high temperatures for a long time, has a long service life, and is easy to replace.
The hot - air circulation system consists of a fan that can operate continuously at high temperatures and a suitable air duct, improving the temperature uniformity in the working chamber.
The partition is upgraded (the partition is made of stainless - steel plate with punched holes, which can solve the problem of uneven placement of items on the previous grid).
The partition strip is upgraded: (first, a large number of partition strips are welded inside the inner tank, and when the partition is placed, it is like a drawer - type pull - out).
The loading brackets in the box can be adjusted freely.
3. Control Introduction
Adopt a liquid crystal display controller with multi-segment programming; it has temperature, humidity, and timing functions, and the temperature control is accurate and reliable.
Working time: The cycle range is 0 - 99, and a maximum of 24 working time segments can be set. The setting range of each segment is 0 - 99 hours; when the cycle is set to 0, it is in a continuous working state.
The upgraded sound and light alarm environmental scanning microcomputer chip has a more powerful data processing function.
Functions such as over-temperature alarm, timed shutdown, power recovery, parameter encryption, and temperature correction are available.
It has a compressor start delay function to effectively ensure the service life of the compressor; and it also has an automatic defrosting function.
It has a power-off recovery function. After the external power supply suddenly fails and then comes back on, the equipment can automatically resume operation according to the original set program.
4. Security Settings
Consider the ultimate safety protection design to realize triple safety protection functions for personnel, samples and equipment: sensor fault alarm, overtemperature alarm, independent over-uplift preventer, independent over-temperature protector, over-current trip protection, etc.
