NA300D single point wall-mounted gas detection alarm
First, the product overview
1.1 Overview
The NA-300D single-point wall-mounted gas detection alarm (hereinafter referred to as the alarm) is a fixed type of instrument that can continuously detect the concentration of flammable gas, oxygen concentration or toxic and harmful gas in the working environment. The NA-300D single-point wall-mounted gas detection alarm detects the gas concentration by natural diffusion method. The large-screen color liquid crystal display displays the concentration value of the leaked gas in real time. The sound and light alarm signal is activated immediately after the preset alarm point; the instrument adopts embedded micro Control technology, infrared remote control, full Chinese setting menu, simple operation, complete functions, high reliability, the performance of the whole machine is at the domestic leading level.
