Rubber Automatic Oxygen Index Equipment Limiting Oxygen Index Chamber
It has the following advantages: high-precision oxygen sensor, digital display, high precision, long life, simple structure, easy to operate, without going through the formula, panel-style operation, gas pressure. Adopting table control method to ensure its accurate readingsconvenience, and high reliability. The use of imported oxygen analyzer control oxygen Gas passage adopts high pressure connector to prevent air leaks effectively.
Application:
It is suitable for the determination of the combustion properties of materials such as plastics,
rubber, fibers, foams, films and textiles, that is, the concentration percentage of the
lowest oxygen in which the polymer just maintains combustion.
