Vistanomics’ Eco Badge® Kits are designed to measure ambient ozone concentration levels even in areas that monitoring stations cant and are ideal for bottled water companies. Badges clip to shirts or jackets, leaving both hands free. The device gives both one-hour and eight-hour readings in a range of 0.025 to 0.120 ppm with .06 and is more sensitive than handheld sensors. Kits for the waterproof version include a waterproof badge holder, 20 test cards and instructions.www.ecobadge.comgws@ecobadge.com
