Oxygen concentration detector/transmitter GAir-O2

The GAir-O2 intelligent oxygen transmitter is a fully intelligent gas transmitter designed using the most advanced ultra large scale integrated circuit technology, international standard intelligent technology level design technology, and proprietary digital analog hybrid communication technology. The product has communication and self diagnosis functions, and is easy to install and maintain. The advanced performance of typical intelligent on-site monitoring instruments has been fully developed, which greatly meets the requirements of high reliability of industrial on-site safety monitoring equipment, and is widely used in environmental protection, test equipment, medical equipment, chemical medicine and other industries.

Fully realize the digitization and intelligence of two-wire gas transmitters;

4-20mA signal and standard Rs232 digital signal output, capable of real-time communication with computers;

Plug and play international standard intelligent sensors make on-site maintenance very convenient;

Unique LCD with backlight design technology, the observation and maintenance of on-site equipment are no longer troubled by changes in light;

Full range digital compensation;

The three explosion-proof buttons enable the transmitter to be freely configured on site, such as viewing, setting, and calibration;

■ Design of intrinsically safe circuits and explosion-proof enclosures, ensuring safe, convenient, and fast on-site maintenance;

The entire shell can rotate 360 degrees according to installation requirements.
