ATEX Combustible and Toxic gases H2s, Co, O2 LEL Fixed Gas
Detectors for industrial gas detection application
Descriptions:
This series of gas detection transmitters adopt the most advanced
ultra-large scale integrated circuit technology and are designed by
the international standard intelligent technology level. It is a
completely intelligent gas detection transmitter designed by
digital and analog hybrid communication technology. The intelligent
gas detection transmitter has advanced technology, excellent
performance, high stability, communication and self-diagnosis
functions, easy installation and maintenance, and the advanced
performance of typical intelligent field monitoring instruments has
been fully demonstrated, which greatly meets the needs of industry.
On-site safety monitoring requires high reliability of equipment.
It is widely used in petroleum, chemical industry, metallurgy,
refining, gas transmission and distribution, biochemical medicine
and other industries. The instrument is compatible with various
control alarms, PLC, DCS and other control systems, which can
realize remote detection, control and alarm.
