EST-10-Ⅱ series recording gas detector is an intelligent hand-held alarm with high precision and low power consumption, which uses advanced electrochemical technology to detect the concentration of toxic gases in the air.
EST-10-ⅱ series is a natural diffusion gas detection method (hand-held external pump can be selected), and the sensitive element adopts advanced electrochemical toxic gas sensor, which has high sensitivity and excellent repeatability; With an LCD screen, the concentration value of target gas can be observed online on site; With two-stage alarm output, the acousto-optic alarm signal will be started immediately when it exceeds the preset alarm point; With soft/hard calibration methods, calibration can be completed without opening the cover; There is a memory chi inside the instrument, which can store 100,000 pieces of data. USB is connected to the computer to export data tables.
