Simultaneously detects oxygen, combustible gases, hydrogen sulfide, and carbon monoxide.
This gas detector detects four types of gases (Type A): oxygen (O2), combustible gas (COMB), hydrogen sulfide (H2S), and carbon monoxide (CO), or three types of gases (Type B or C), and displays the concentration of each gas simultaneously. It also issues an alarm when it detects gas concentrations that exceed pre-set values (alarm levels), helping to prevent accidents caused by oxygen deficiency, gas explosions, and gas poisoning.
