HERMES™ Personal Mercury Monitor™


Product Details

The World's Smallest Mercury Monitor


The HERMES has dimensions of 4 x 3 x 1.5 inches and weighs only 0.75 lb (340 g).  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.



  • Monitoring of exposure to individuals in the workplace
  • Monitoring and control of mercury in industrial settings
  • Personal exposure monitoring for studies of health effects of air pollutants
  • Long-term monitoring at remote locations where power is highly limited
