ES-G334 Liquid crystal LCD gas sensor

ES-G334 Liquid crystal LCD gas sensor used to detect the gas concentration parameters in the air environment. When the concentration exceeds the preset alarm value, it will send out sound and light alarm signals to remind users to timely Take safety measures to prevent explosions and poisoning accidents, so as to ensure the safety of life and property.
