Pump type voice gas detector (hereinafter referred to as detector) is a kind of safety equipment which can continuously use to detect the concentration of leaked gas. It adopts advanced integrated circuit technology, 32-bit embedded microcomputer chip control and imported 16 bit ultra-high resolution ADC detection special chip. The calculation speed is faster and the test data is more accurate and stable. The detector uses a 2.4-inch high-definition LCD color screen,through Chinese and English interface and Chinese and English voice prompts,users can quickly understand the product, easy to use and maintain; the detector uses aluminum alloy shell, USB charging interface, built-in 2900ma large capacity lithium battery and high-end vacuum suction pump, high-quality imported gas sensor, with excellent sensitivity and excellent repeatability; P PM and Mg / m3 range unit switch with one key, fast reaction speed, strong anti-interference ability,stable and reliable performance, in the domestic leading level.
