Display mode: 2.1 inch bright color LED display, 4-digit 8-segment digital + graphic display. The sensor shell is made of aluminum alloy to ensure that the sensor is not affected by the adsorption of the shell. The detector adopts imported high-precision gas sensor, which has the function of intelligent control sensor high-concentration flooding protection. The detector shell adopts the thickened explosion-proof aluminum alloy shell and the thickened explosion-proof glass panel to ensure the long-term stable work of the product in various industrial explosion-proof environments.
