Description:
OC‑901 portable CH4S gas detector is an industrial‑grade portable gas monitoring instrument. It is equipped with original imported electrochemical sensor for CH4S (Methyl Mercaptan / Methanethiol). Built‑in pump‑suction sampling realizes fast gas absorption and rapid response, which can accurately measure CH4S concentration and detect gas leakage on site.
CH4S is colorless gas with strong rotten‑cabbage offensive odor. It is both toxic and highly flammable, explosive limit 3.9%‑21.8% VOL in air. High concentration inhalation will irritate eyes and respiratory tract, suppress central nervous system, and may cause respiratory paralysis. Note that strong odor will lead to olfactory fatigue under continuous exposure, smell cannot be used as reliable judgment for hazard. It is generated in petroleum refining, sewage degradation, landfill gas, pesticide and fine‑chemical synthesis processes. Leakage from pipelines, reaction vessels and storage cylinders brings poisoning and explosion risks for on‑site staff. This instrument is widely used for refinery patrol, sewage treatment plant monitoring, landfill site inspection, pesticide‑chemical workshop check and confined‑space spot‑check.
The device is fitted with a 2.4‑inch color display, supporting free switch between English and Chinese operating menu. Once gas concentration exceeds alarm threshold, voice, audible‑visual and vibration triple alarm will be activated to remind site personnel of potential hazards.
Built‑in 3.7V 4000mAh rechargeable lithium battery provides continuous working time more than 10 hours. Back clip design allows easy wearing during field inspection. IP65 protection and Ex ib IIB T3 explosion‑proof rating make it capable of complex and harsh industrial environment. Alarm data storage function supports historical record review. Aluminum alloy carry box is supplied for convenient transportation and storage.

It can be combined with 1~4 different gas sensors for different gas type.
2.4 inch colorful display, support both English and Chinese operating menu.
With audible-visual-vibration alarm mode, also with the voice alarm.
With a back clip, which is easy to carry when working.
Powered by rechargeable battery with big capacity which support a long working period.
