Personal Mercury Monitor | 2.B Tech

It has a built in GPS so that mercury measurements may be logged continuously along with geographic location. By folding the optical path in the shape of a "U," it was possible to achieve a 15-centimeter path length, enabling extremely sensitive measurements of mercury in ambient air.

Application :

• Monitoring of exposure to individuals in the workplace
• Monitoring and control of mercury in industrial settings
