Liaocheng Weilu Electronic Technology Co., Ltd. specializes in the production of fixed, portable oxygen alarm, handheld oxygen leak detector, oxygen leak alarm, oxygen detector, oxygen leak alarm, oxygen concentration alarm, oxygen detection alarm.The company cooperates with the United States, Britain, Germany sensor companies, the products use pure imported sensors, to achieve high detection accuracy, stable performance, reliable quality , anti-poisoning, strong anti-interference ability, etc., and can detect flammable, explosive or toxic gases for a long time. 02 02WL-1000/2000/3000 oxygen gas detector is a high quality alarm developed and produced by our company. Using ultra-bright LCD display, the display is intuitive and clear, real-time display of the concentration of the gas to be measured, and the Chinese menu operation is easy to use, easy to operate, easy to learn and understand. The oxygen gas detector adopts imported sensors, responsive, anti-toxic, anti-corrosion, anti-wind and sand, etc., the test procedure is controlled by artificial intelligence microcomputer, reasonable workflow, simple and convenient, complete functions, and has a variety of adaptive capabilities; each channel has independent two-level gas concentration, public level 3 gas concentration, fault acousto-optic alarm, and the corresponding relay signal output 4-20mA output.
