Compost Degradation Tester GBDA-120 Introduction GBDA series intelligent compost degradation tester is our company's many years of research and development technology and application experience in biodegradation. It is designed in full compliance with standards such as GB/T19277.1 and ISO14855-1. The mass of carbon dioxide released during biodegradation can be detected automatically, and the biodegradation percentage of degradable materials can be determined. Test principle The test material and inoculum are mixed and poured into the reaction vessel. Under the condition of aerobic composting, the organic compounds of the test materials are decomposed by microorganisms into carbon dioxide (CO2), water (H2O) and the mineralized inorganic salts and new substances of the elements contained in them, and the emitted carbon dioxide (CO2) is measured by a continuous infrared analysis sensor ( CO2) to determine the final biodegradability of the test material. Standard ISO14855-1, ASTM D 5338, ASTM D 6400, JIS K 6953 GB22047, ISO 17556-2012
