1、 Product Overview
This instrument is a new product carefully developed by me for emergency detection of sudden environmental air accidents. Suitable for emergency detection, concentration exceeding alarm, etc. in conventional, fire-fighting, flammable and explosive situations; Detection of toxic and harmful gases in occupational health facilities; Especially suitable for emergency accident monitoring with unclear pollution sources. The technical performance indicators of the detection alarm device comply with the relevant standards issued by the National Environmental Protection Administration and have successfully passed the testing of the national quality supervision and inspection center. The explosion-proof level is: Ex d ib IIB T4 Gb。 By utilizing high-performance 32-bit processors, color touch displays, sensors, and advanced technologies in the field of new materials, we strive to provide users with a high-quality detection and alarm device that is reliable in quality and stable in performance.

2、 Execution standards
GB 12358-2006 General Technical Requirements for Workplace Gas Detection and Alarm Devices
