RAE Systems' third-generation photoionization detector (PID)-based instruments, the MiniRAE 3000 and ppbRAE 3000, are intended for use where hydrocarbon-based chemicals pose a toxic threat. The MiniRAE 3000 has an extended measurement range of 0.1 parts per million (ppm) to 15,000 ppm. The ppbRAE 3000 offers an extended measurement range of 1 part per billion (ppb) to 10,000 ppm. Both products feature a large back-lit graphical display with graphical charting capability and easy viewing in any light condition. The products include more than 200 built-in correction factors for accurately measuring a range of chemicals. Both instruments have optional charging cradles with a USB interface for downloading up to six months of data to a computer for either analysis or record keeping.
