Using a 3rd generation photoionization detector (PID) and built-in correction factors for more than 200 compounds, the ppbRAE 3000+ is one of the most advanced VOC monitors for parts-per-billion (ppb) detection. It measures the presence of VOCs from 1ppb-10,000ppm with a three-second response time. Optional built-in Mesh Radio enables real-time monitoring of instrument readings wirelessly. Another option is Bluetooth, which can relay readings and alarm status up to 2 miles to a RAELink 3 wireless transmitter. And a rugged housing, large display, and large keys that can be operated with three layers of gloves all make for a unit that’s easy to use and maintain
