Beautiful design. WG7000 adopt fuel-cell sensor as its core component that can inspect accurately concentration of the breath alcohol, with rapid response. WG7000 has compact keyboard, operation menu, admirable human-device interface and four languages application, which makes operation more concise and convenient.
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.
The products is meet JJG 915-2008 carbon monoxide detection alarm, JJG 695-2003 hydrogen sulfide gas detector, JJG 693-2011 combustible gas alarm, JJG 365-2008 Relevant requirements of the verification regulations of the electrochemical oxygen analyzer.
Industry standard RS-485 standard signal output.
Alarm light, fault light, running light prompt.
Have two relay outputs.
Independent sound and light alarm active output interface.
Use 128*64 high-definition dot matrix LCD screen, unique large character design, observe the output value is very clear.
Two relays can be designed for different alarm values, which is convenient for separate control for early warning and alarm.
Infrared remote control function, easy to operate from a long distance without opening
It can be widely used in the city gas transmission and distribution pipeline, oil, petrochemical industry refineries, chemical plants, metallurgical industry, power industry and other places that may produce gas leakage.
