Working Principle:

The sample is placed in a sealed space. Under constant temperature conditions, when the vapor pressure of the sample and the surrounding air reach equilibrium, the water vapor pressure of the gas space is taken as the sample vapor pressure. That is, the decimal form of the relative humidity of the air in the top space of the sample chamber is the water activity of the sample.

• Modula Design, Automatic Stirring of Reactors: It can accommodate more than 24 degradation reactors, and each reactor is equipped with an automatic stirring device as standard, which can achieve regular and automatic stirring without manual intervention.
• Self-developed Unit for Infrared Principle Sensors: CO2 gas sensors, air mass flow controllers, temperature and humidity sensors, and pressure sensors are shipped with their own calibration and measurement to facilitate users to quickly obtain certification and approval.
• Online Real-time Monitoring of CO2: Multiple modes can be selected for CO2 monitoring during the degradation process, real-time continuous monitoring and regular accumulation monitoring, and the PC and mobile terminals are linked.
• Microbial Control Tech: Unique compost activation technology and microbial capacity determination technology can provide improved compost and vermiculite.
• Data Output in Multiple Formats:  PC software control, data mapping, test data supports multiple formats of output.
• Test Processing Fully Automated: An external water tank and automatic condensation reflux device can be installed to ensure that the reactor always maintains the required humidity range during the test.
