Three test chambers operate independently, each equipped with its own humidity control, airflow management, regulation of various gas concentrations, ethylene removal devices, lighting systems, sterilization systems, and drainage systems.
Utilizes a built-in microcomputer system for automated control and data processing. You can manually switch between chambers to display the temperature and humidity of each cavity, as well as the concentration of oxygen, nitrogen, carbon dioxide, and ethylene.
Features a 24-inch 100,000-color touchscreen, which is used to set the parameters of each cavity and control operations individually. It displays detailed data and real-time work status.
Incorporates built-in ozone sterilization, manual activation for sterilization, and the option to set the sterilization time.
Includes an integrated ethylene catalytic removal device and a gas displacement pump to efficiently control ethylene concentration with rapid degassing.
Utilizes high-precision imported sensors to accurately monitor various gas concentrations and ethylene levels.
The sterilization system relies on ozone sterilization, with a manual activation button for sterilization, automatic control of sterilization time, and automatic shutdown when the set time is reached.
Temperature control is achieved through heating wire heating and scroll compressor cooling for stable performance with minimal noise. It uses the PID algorithm with solid-state relay control for durability and uniform temperature heating.
Humidity control is maintained through high-frequency fog humidification, offering a broad humidification range without affecting chamber temperature. Each chamber's humidification system operates independently, automatically humidifying and maintaining the desired humidity level.
The inner walls of each cavity are constructed from stainless steel, with a special double-layer glass door, and the shell is made of specialized color steel plate.
Additional features include transparent windows, an anti-condensation drainage system, built-in lighting, and a user-friendly self-entry box design.
Nine test chambers operate independently. Each chamber has its own control over humidity, airflow, and the concentration of various gases. It also features an ethylene removal device, a lighting system, sterilization equipment, and a drainage system.
Equipped with a built-in microcomputer system for automated control and data processing. Users can manually select the chambers to display temperature, humidity, and data related to oxygen, nitrogen, carbon dioxide, and ethylene concentrations.
Boasts a 24-inch, 100,000-color touchscreen for individual parameter configuration and operational control of each chamber. Detailed data and real-time work status are prominently displayed.
Incorporates an integrated ozone sterilization system with a manual sterilization button and adjustable sterilization time.
Comes with an ethylene catalytic removal device and a gas replacement pump to efficiently manage ethylene concentrations, ensuring rapid degassing.
Utilizes imported high-precision sensors to accurately detect various gas concentrations and ethylene levels.
The sterilization system relies on ozone sterilization with manual sterilization activation, automatic control of sterilization time, and automatic shutdown upon reaching the pre-set time.
Temperature control is achieved using heating wire and scroll compressor cooling, delivering consistent performance with minimal noise. The PID algorithm, in combination with solid-state relay control, extends the equipment's service life and provides uniform temperature heating. Temperature control for each chamber is manually set.
For humidity control, it uses high-frequency atomization humidification with a wide humidification range. This method ensures long-term humidification without affecting the chamber's temperature. Each chamber's humidification system operates independently and automatically maintains the set humidity level.
The inner walls of each chamber are constructed from stainless steel, with a special double-layer glass door and a shell made of specialized color steel plate.
Additional features include transparent windows, an anti-condensation drainage system, built-in lighting, and a user-friendly self-engaging box design.
