手持式多合一气体检测仪 Product Name: Handheld All-in-One Gas Detector
SDH401-B Product model: SDH401-B
Product introduction:

SDH401-B portable gas detection alarm device is a detector that can detect multiple gases at the same time, and can continuously measure flammable, O2, CO, H2S and other toxic gases in the ambient air. It can detect 4 gases simultaneously. The meter's waterproof design incorporates a rubber case to meet the most demanding requirements of harsh environments. The detector uses a pumping method to detect the gas, and the sensitive element uses a high-quality gas sensor, which has excellent sensitivity and excellent repeatability; the instrument uses embedded microcomputer control, has a variety of adaptive capabilities, and uses a graphic LCD display, which is intuitive and clear . The Chinese menu has simple operation, complete functions, high reliability, and the performance of the whole machine ranks domestically leading.
