Oxygen Detector Meter-Oxygen Content Test In The Confined Space Of Mine Shafts
The EST-10-Ⅱ-O2 series oxygen detector detector is a high-precision and low-power intelligent handheld alarm that uses advanced electrochemical technology to detect the concentration of toxic and harmful gases in the target gas.
The EST-10-Ⅱ-O2 series adopts a natural diffusion gas detection method (with an optional handheld external pump), and its sensitive components are advanced electrochemical toxic gas sensors, featuring high sensitivity and excellent repeatability. It is equipped with an LCD liquid crystal display screen, allowing for on-site online observation of the concentration value of the target gas. It features two-level alarm output. Once the preset alarm point is exceeded, the audible and visual alarm signal will be immediately activated. It has both soft and hard calibration methods, and the calibration work can be completed without opening the cover. The instrument is equipped with a storage chip inside, which can store 100,000 pieces of data.
