SafeAir badges - Chemical detection badges
The SafeAir passive is a personal equipment dedicated to monitoring exposure to toxic gases over exposure times ranging from 15 minutes to 24 hours. Small and discreet, the SafeAir chemical detection badge detects the presence of gas even at very low concentrations by changing color.
The SafeAir passive sampling badges are very popular to measure and control concentrations of aromatic isocyanates such as toluene diisocyanate (TDI) or diphenylmethane diisocyanate (MDI), formaldehyde, hydrazine , mercury, ozone, phosgene, etc ... Detailed description
The SafeAir badge
Easy to use, precise, economical and requiring no particular technical skills or calibration, the SafeAir badges consist of a colorimetric chemical detection badge with direct reading and a color comparison table.
Most of them are waterproof and all are insensitive to relative humidity. The color changes and instantly indicates to its user the presence of the chemical hazard. Detection is done by a flat sensor integrated in the badge allowing a uniform and stable color.
SafeAir chemical detection badge with double threshold
Mercury and 1,1-dimethylhydrazine SafeAir badges provide the user with two independent threshold levels. The front of the badge indicates a threshold level while the back provides a second. This unique feature allows the badge to be used as an inexpensive range finder.
The chlorine badge distinguishes on one side chlorine and on the back chlorine dioxide, thus discriminating these two gases very often present at the same time
Color comparator for SafeAir badges
For better interpretation and precision on the quantity of gas to which the wearer has been exposed, all you have to do is take the color comparator, slide the SafeAir chemical detection badge into it and find the color corresponding to the exclamation point on the badge to know the exact gas exposure.
