General Description
The SafeAir badges are designed to detect specific vapors and gases at exposure doses well below hazardous levels, often at ppb levels. Morphix offers SafeAir badges for fourteen different chemicals. The SafeAir badge provides an immediate indication when a specific chemical hazard is present. The color chemistry sensor in the SafeAir badge will change color in the presence of the targeted chemical. The SafeAir badges were designed for industrial hygiene and safety applications but may also be useful for first responders. There is no calibration, extra equipment, power or laboratory analysis. SafeAir badges are available for the detection of ammonia, aromatic isocyanates (TDI and MDI), carbon monoxide, chlorine, chlorine/chlorine dioxide, formaldehyde, hydrazine, hydrogen chloride, hydrogen sulfide, mercury, ozone, phosgene, and sulfur dioxide.
Technical Description
The SafeAir badges employ colorimetric chemistry on a dry flat sensor that is sensitive and highly selective to the target chemical. The unique design minimizes the effects of humidity and velocity and most sensors are completely water proof. SafeAir badges are available for the detection of ammonia, aromatic isocyanates (TDI and MDI), carbon monoxide, chlorine, chlorine/chlorine dioxide, formaldehyde, hydrazine, hydrogen chloride, hydrogen sulfide, mercury, ozone, phosgene, and sulfur dioxide.
