Description:
OC-850 portable multi gas detector is a customizable handheld industrial toxic & malodorous flue gas monitoring terminal, equipped with five independent high-selectivity electrochemical sensor combination: H₂S Hydrogen Sulfide, CO Carbon Monoxide, SO₂ Sulfur Dioxide, NO₂ Nitrogen Dioxide, NH₃ Ammonia.
All five gases adopt separated independent electrochemical sensors, effectively reduce cross interference among mixed acid, alkaline and toxic gases. It can precisely detect various toxic and irritant flue gas produced from waste incineration, metallurgical smelting, chemical reaction, sewage fermentation and industrial waste gas emission.
The detector supports dual sampling modes: standard diffusion passive sampling and optional 1L/min pump suction active sampling, suitable for stack sampling, underground sewage tanks, closed chemical workshops and waste disposal sites gas collection. Built-in stainless steel anti-corrosion filter screen blocks corrosive acid mist, smoke dust and water vapor to protect internal sensors. LCD screen synchronously displays real-time concentration, gas name and over-limit alarm status of five gases.
With Ex ib IIB T3 explosion-proof certification and IP65 dustproof & waterproof grade, triple sound-light-vibration over-limit alarm, stores up to 9999 groups alarm records. Wide working temperature -40℃~70℃, 100 hours long standby without pump. Widely applied to waste incineration plants, metallurgical factories, sewage treatment plants, chemical enterprises, environmental law enforcement flue gas sampling and industrial waste gas safety patrol.
