Product Description
【Scope of Application】:
This device is used to determine the final aerobic biodegradation ability and disintegration degree of test materials such as fibers and plastics under controlled composting conditions by measuring the amount of carbon dioxide emitted. It complies with standards such as GB/T19277.1-2011, ISO 14855.1-2012, ASTM D5338, GB/T 20197-2006, EN13432, EN14046, JIS K6953, etc.
【Related Standards】:
1. GB/T19277.1-2011
2. ISO 14855.1-2012
3. ASTM D5338
4. GB/T 20197-2006
5. EN13432, EN14046, JIS K6953, etc.
【Instrument Characteristics】:
(1) The entire experimental period is covered by the software for automatic data measurement, significantly reducing labor costs while ensuring data reliability;
(2) Data is saved in case of power failure, and the test is automatically conducted upon power restoration;
(3) Gas sensors continuously test the CO2 production during the plastic sample degradation process;
(4) Gas sensors can monitor the O2 content in the reactor, facilitating process control;
(5) Gas sensors can measure gases such as H2S and CH4 during the plastic sample degradation process, facilitating overall analysis;
(6) Mass flow meters precisely control the flow rate entering the reactor, providing better parallelism;
(7) The reactor can be controlled at the user-specified temperature;
(8) The air in the reactor is automatically humidified.
