Hydrogen sulfide H2S detector

OC-905 Portable pump-suction H2S gas detector

OC-905 Portable pump-suction H2S hydrogen sulfide gas detector, handheld toxic gas monitor with built-in pump, sound light alarm, used for sewage treatment plant, oil gas industry and confined space safety inspection.

Description

OC-905 Portable pump-suctionH2S hydrogen sulfidegas detector is a professional handheld toxic gas detection instrument equipped with internal sampling pump. The built-in pump actively extracts ambient gas into the sensor chamber, achieving fast sampling and rapid response, which performs well for sampling in confined space and remote detection points. Equipped with high-precision hydrogen sulfide sensor, the device can continuously and stably measure H2S concentration. Real-time readings are clearly presented on LCD screen. Once gas concentration exceeds user-defined alarm value, the unit activates sound and light reminders to warn operators of hydrogen sulfide poisoning hazards in time. Ergonomic lightweight handheld body is easy to carry. Powered by rechargeable lithium battery, it supports long-hour continuous field inspection. This H2S detector is widely used in sewage treatment stations, oil & gas fields, refineries, sewers, landfill sites and tunnel engineering. It is an essential safety testing instrument for preventing hydrogen sulfide toxic gas risks at industrial sites.


Function:

Inspect the gas concentration and alarm when it reaches preset alarm level.

High accuracy, good stability and good repeatability, long working life.

One-key operation to restore to factory default setting.

Adjustable two-stage audible-visual alarm threshold value.

Powered by rechargeable lithium battery with big capacity.

The built-in pump, stable flow rate, can be opened or closed.
