SafeAir Hydrogen Sulfide Detection Badges
Hydrogen sulfide is a colorless gas with a strong odor resembling rotten eggs. Emitted as a byproduct from many industrial processes, hydrogen sulfide is a widely spread pollutant. Continuous exposure to low concentrations generally causes irritation to the mucous membranes. It may also cause headaches and dizziness. At 100–150 ppm the olfactory nerve is paralyzed after a few inhalations, and the sense of smell disappears, often together with awareness of danger.
SafeAir Hydrogen Sulfide badges provide an immediate visual indication of exposure to hydrogen sulfide. When hydrogen sulfide gas is present, the exclamation mark in the triangular window changes color. The intensity of the color change is proportional to the exposure dose. The SafeAir Hydrogen Sulfide badge is a simple, cost-effective solution for hydrogen sulfide detection in the workplace.
Features:
- Highly sensitive and selective to target chemical
- Easy to use
- Ideal for daily employee screening or leak detection
- Measures TWA exposure
- No calibration or laboratory analysis needed
