Purpose Overview 

This product is equipped with devices for constant temperature and humidity control, capable of providing a stable temperature and humidity environment for various stability tests. It is widely used in the pharmaceutical industry, food industry, cosmetics industry, microbiological culture, biotechnology and other fields to test the performance, lifespan and packaging of raw materials. 

Structural features 

This product features a novel and elegant design. The working chamber is made of high-quality 304 stainless steel with rounded corners for easy cleaning. The outer shell is crafted from high-quality cold-rolled steel plates and treated with electrostatic powder coating for strong corrosion resistance. It has a double-door structure, with the inner door being a high-quality tempered glass door, allowing direct observation of the experiments inside without affecting the internal temperature and humidity. The unique air duct design ensures uniform and stable temperature and humidity inside the working chamber. The stainless steel shelves can be adjusted freely in height. 

The true-color LCD touch screen displays real-time temperature, humidity and time. It features a user-friendly interface for easy operation and is more user-friendly. Historical data of the instrument can be viewed. 

It adopts an intelligent operating system, with fuzzy P.I.D. intelligent control. It can be freely set for constant value/multi-segment program operation. It is equipped with a large-capacity memory that can store 250,000 data records and 16,000 event records. 

It has a function to switch between Chinese and English menus. 

User permission hierarchical management: Administrators can create up to 5 sub-users and assign different permissions to them, enabling multi-level management. 

It can automatically record the operation data, operation logs and alarm logs of the equipment, and the original files or unalterable PDF files can be exported through the USB interface of the instrument. 

The screen password lock function can prevent non-experimental personnel from operating at will. 

·Equipped with high-brightness LED lighting and ultraviolet sterilization lamps (limited to the MJ-N series); one side of the box is equipped with a test hole (50mm) for convenient data verification. 

It adopts original imported high-precision temperature and humidity sensors, which are accurate and reliable. Long-term use does not require maintenance. 

The variable-frequency refrigeration system is energy-saving and water-saving, with small fluctuations in temperature and humidity, quick recovery after opening the door, and ensures long-term frost-free operation of the equipment under non-extreme conditions. It adopts compressors of internationally renowned brands and uses environmentally friendly fluorine-free refrigerants. 

The call recovery mode is selectable: stop, resume operation, and continue operation. 

It can be equipped with an embedded micro printer: real-time printing of temperature and humidity data, and the printing time interval can be set by yourself. (Optional) 

4G smart IoT gateway or WiFi smart IoT gateway, which can be remotely monitored intelligently 24/7 via WeChat mini program. It supports alarm push, monitoring of equipment operation status, historical data and curve query, and export of PDF files. (Optional) 

· SMS Alarm Module: GPRS mobile phone SMS alarm (sent to the designated mobile phone through communication software to ensure the safety of the testing process). (Optional) 

We can provide 3Q verification services.
