Product introduction

Explosion-proof portable HS gas detector is a key safety instrument for real-time monitoring of hydrogen sulfide (HS) concentration in industrial environment. Hydrogen sulfide is a highly toxic and flammable dangerous gas, which is commonly found in oil and gas, petrochemical processing, sewage treatment and mine operation environment.

Because HS can cause serious harm to human body at low concentration, even life-threatening, it is necessary to rely on continuous monitoring and early warning to ensure the safety of workers.

The equipment is designed with intrinsic safety and flameproof, and can run stably in flammable and explosive environment.

What is an explosion-proof portable HS gas detector?

Explosion-proof portable HS detector is a hand-held gas detection device, which is used to continuously measure the concentration of hydrogen sulfide in the air and give an alarm in time in case of danger.

From a technical point of view, the explosion-proof design ensures that:

• Will not ignite the surrounding explosive gas environment.
• The internal circuit sparks are completely isolated.
• Meet industrial explosion-proof standards, such as Ex ia IIC T4 Ga.

Therefore, it is suitable for hazardous environment in Zone 0/Zone 1.

principle of operation

The equipment adopts diffusion sampling+electrochemical sensing technology;

HS in the air enters the sensor through natural diffusion.
Electrochemical sensor reacts with HS.
Generate a weak electrical signal proportional to the concentration.
The MCU converts the signal into a ppm concentration value.
The screen displays the gas concentration in real time.
Triggers an alarm when the safety threshold is exceeded.

Alarm modes include:

• Sound alarm (buzzer)
• LED light alarm
• Vibration alarm

Ensure that personnel can be reminded in time even in high noise or low visibility environment.

Why is it necessary to monitor hydrogen sulfide (HS)?

Hydrogen sulfide is an extremely dangerous industrial gas, and its main risks include:

• Poisoning at low concentration (ppm level)
• Damage to the respiratory system and even coma.
• High concentrations can be quickly fatal.
• Common in confined space and anoxic environment.
• It is potentially flammable.

Because HS is colorless and its sense of smell will be paralyzed at high concentration, it is extremely dangerous to judge only by smell, so professional testing equipment must be used for continuous monitoring.
