Testing Principle
The test material of this method is a mixture of inoculum of decomposed compost and inert materials (such as sea sand and vermiculite). By controlling the humidity, oxygen permeability and temperature of the compost container, the sample to be analyzed in the reaction chamber is under the action of microorganisms. The biodegradation reaction is carried out through respiration, and oxygen becomes carbon dioxide and is discharged through respiration. The amount of carbon dioxide released is measured by weighing the absorption device equipped with soda lime and sodium talc, and the decomposition rate is calculated by regular measurement.

Features
Precise control of experimental conditions
- 360℃ air bath temperature control, intelligent PID module algorithm can accurately control the temperature required for the reaction.
- Intelligent detection of humidity, automatic humidification of the external water tank and condensate return technology to ensure that the standard requirements for the water content of the inoculum are met within the test cycle.
- Intelligent air tightness monitoring, equipped with high-precision brand flowmeters, real-time monitoring system sealing performance, providing suspected leakage alarm function, ensuring that each composting container can maintain sufficient aeration conditions during the test.
- Support accidental power failure during the test period, and the test function will continue to be restored after incoming calls.
- The channels can be freely combined, and the blank, reference, and sample modes can be freely set for independent testing.
- Real-time display of carbon dioxide quality curve and biodegradation rate curve.
- Support remote monitoring of the experimental process through mobile phones, ipads, and PCs.
Result validity analysis
- The software contains a result validity judgment module, which can display the biodegradation rate of the reference material after 45 days, the carbon dioxide (mg) produced by the blank container within 10 days before the experiment (mg)/the volatile solids of the inoculum (g), and the biodegradation rate of 18 channels Relative deviation.
- The report template contains parameters such as the average carbon dioxide value of the blank group, theoretical carbon dioxide, generated carbon dioxide, biological decomposition rate, relative decomposition rate and time.
Personalized customization
- The tail gas analysis module can be customized to meet different scientific research needs, such as methane, ammonia, nitrogen dioxide, hydrogen sulfide, sulfur dioxide, odor, VOC and other gas characteristic parameters.
- Support 12/18/24/30 station customization, support data mean mode customization.
