Description:
OC‑901 portable H2S & NH3 & Ex gas detector is an industrial‑grade portable multi‑gas monitoring instrument. It is equipped with original imported electrochemical sensors for H2S (Hydrogen Sulfide), NH3 (Ammonia) and catalytic combustion sensor for Ex (Combustible Gas). Built‑in pump‑suction sampling realizes fast gas absorption and rapid response, which can accurately measure H2S, NH3 and Ex concentration at the same time.
H2S is highly toxic corrosive gas with rotten‑egg smell, NH3 is irritant toxic gas, Ex represents combustible gas which may cause explosion when reaching certain concentration. These gases often appear in sewage treatment plant, waste transfer station, petrochemical and chemical production site. This instrument is widely used for sewage plant inspection, chemical workshop patrol, petrochemical plant, confined‑space operation and environmental emergency 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.
OC‑901 supports customized 1‑4 sensor channels. It can detect H2S, NH3 and Ex simultaneously, and also supports adding CO, O2, TVOC and other gas sensors for combined multi‑gas measurement.
Features:
It used original imported sensor with good quality and high accuracy.
It with the inner pump, sampling speed more fast.
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.
