Features
- The product shell is made of high-quality steel plates and is electrostatically sprayed on the surface. The design is elegant. The working chamber is processed and made of high-quality stainless steel, which is corrosion-resistant and resistant to aging. The inner walls have a rounded transition.
- It adopts an intelligent microcomputer liquid crystal display control system, featuring functions such as timing, alarm, and over-temperature protection.
- The brand compressor uses non-chlorofluorocarbon (CFC-free) environmentally friendly refrigeration technology. The gentle air circulation ensures uniform temperature inside the box.
- The balanced control of cooling and heating ensures a small temperature fluctuation and more precise temperature control.
- The tempered glass observation window makes it easy to observe the changes of items inside the box. The magnetic adhesive strips provide a secure seal, facilitating opening and maintaining excellent sealing performance.
- Using ultrasonic humidification, the humidity control is stable. The humidity fluctuation range is ±5 – 8% RH. It also has the function of automatically shutting off when there is insufficient water.
- It is equipped with multiple safety measures such as compressor overheating protection and instrument failure protection to ensure the safety of the experiment.
- It can be equipped with functions such as printer, 485 interface, USB storage, and SMS alarm.
Upgrade content: (9-point test temperature)
- Inner liner thickness upgrade: The original thickness was 0.8mm, and the upgraded thickness is 1.0mm.
- Increased automatic defrosting capability, improving the equipment’s operational efficiency, reducing energy consumption and extending service life.
- Fan upgrade, from capacitor fan to axial brushless fan, ensuring uniform temperature distribution inside the box.
