Product Introduction
MA11-4EA2813A consists of four MA11-EA2813A oxygen analyzers, which communicate with the upper computer through Ethernet or RS485. Modular combination, each unit is independent of each other and can be quickly replaced and combined without affecting the continued use of other channels. The application is simple, flexible, and has the advantages of advanced technology, high precision, fast response, stable performance, complete functions, easy operation, and continuous gas analysis process. Widely used in atmosphere protection furnaces, reflow soldering and other equipment that require simultaneous monitoring of multiple areas.

Product Features
1. The instrument is composed of multiple small volume oxygen analyzers;
2. The instrument is equipped with an RS485 communication port and an Ethernet interface that complies with the Modbus TCP protocol;
3. The analyzer can communicate unidirectionally or bidirectionally with the upper computer.
4. Original imported zirconia oxygen sensor with high measurement accuracy, fast response, and long lifespan;
5. Built in temperature and pressure sensor modules, pipeline pressure sensors;
6. Comes with air path blockage alarm and self-protection function. After the air path is blocked, the vacuum pump will automatically shut down, stopping the operation of the oxygen sensor, which can effectively extend the service life of the vacuum pump and sensor;
7. Modular combination allows for quick replacement of combinations without affecting the continued use of other channels;
