Product Overview
Hydrogen sulfide detector is a safety detection instrument for industrial combustible gases, toxic gases and harmful gases according to the standard.
. The detector is designed with a dual-cavity structure and has functions such as on-site display, infrared remote control zeroing and calibration. Two-wire non-polar power supply and signal transmission, easy and convenient installation, economical wiring.
Main features
◆ Concentration display and status indication
On-site concentration display and on-site status indication can display the operating status of the detector in real time.
◆ Digital signal
Compared with the analog signal standard current signal, there is no need to debug before replacement. The position of the gas detector can be changed at any time, making maintenance more convenient. Advantages: High accuracy, long transmission distance, and good anti-interference.
◆ Accurate measurement
The sensor adopts imported gas sensitive components with high accuracy, small zero point drift and good anti-poisoning performance.
◆ Explosion-proof design
Can be used in factory conditions and hazardous locations.
◆ Convenient maintenance
The sensor adopts digital module design, and no zeroing or calibration is required during on-site replacement.
◆ Sound and light alarm (optional)
Special explosion-proof sound and light alarm lights are optional to realize on-site sound and light alarm.

Product installation
◆ Installation methods include wall-mounted, pipe-holding, and pipe-through types
◆ Matching controller-type gas alarm controller.
◆ Gas detectors should be installed in places where gas is prone to leakage. The specific location should be determined based on the specific gravity of the detected gas relative to air.
When the specific gravity of the detected gas is greater than the specific gravity of air, the gas detector should be installed at a distance (~) from the ground, with the sensor part facing downwards.
When the specific gravity of the detected gas is less than the specific gravity of air, the gas detector should be installed at a distance (~) from the ceiling, with the sensor part facing downwards.
◆ In order to use the gas detector correctly and prevent the occurrence of gas detector failure, please do not install it in the following locations
, places directly affected by steam and oil fume
, air supply openings, ventilation fans, rooms Places with large air flow such as doors
Places with a lot of water vapor and water droplets (relative humidity)
Places with temperatures below or above ℃
Places with strong electromagnetic fields.

Little knowledge about hydrogen sulfide
Hydrogen sulfide, with the molecular formula and molecular weight, is a flammable acidic gas under standard conditions. It is colorless. It smells like rotten eggs at low concentrations and is highly toxic. Olfactory Threshold Even low concentrations of hydrogen sulfide can damage the human sense of smell. When the concentration is high, there is no smell (because high concentrations of hydrogen sulfide can paralyze the olfactory nerve). Using your nose as a means of detecting this gas is fatal. The molecular weight is vapor pressure, flash point is ℃, melting point is, boiling point is, relative density is (air). Easily soluble in water, also soluble in alcohols, petroleum solvents and crude oil. The flash point is ℃. Hydrogen sulfide is a flammable and hazardous chemical that can form an explosive mixture when mixed with air. It can cause combustion and explosion when exposed to open flames or high heat. Completely dry hydrogen sulfide does not react with oxygen in the air at room temperature, but it can burn in the air when ignited. It burns during blowout during drilling and downhole operations, and the combustion rate is only about 10%. Hydrogen sulfide produces a blue flame when burned and produces toxic sulfur dioxide gas, which can damage human eyes and lungs. In addition to oxygen or air, hydrogen sulfide can also burn in chlorine and fluorine.
