An Oxygen sensor Oxygen gas detection probe Overview oxygen gas detection probe oxygen sensor is developed by our company functional and practical, easy to operate flammable / toxic gas alarm. With my company combustible / toxic gas alarm controller composed of industrial gas alarm systems. The controller can also be linked via a 485 signal to the monitoring center computer, and through the company-specific monitoring software for off-site concentration scene query, thus constituting a remote monitoring, local monitoring, on-site monitoring of multi-level monitoring network, greatly improve the monitoring of real-time, accurate.
