    The NEO is one of the most advanced handheld VOC (Volatile Organic Compound) monitors available for ppb (parts per billion) detection. The NEO offers several models from the most sensitive 1 ppb to a high range up to 15000 ppm for different applications and user selections. Novel designs of the photo-ioniza- tion detector (PID) and ultraviolet (UV) lamp provide outstanding sensitivity, stability and reproducibility.

    Its function is based on the premise that if the instrument is motionless when it is not supposed to be, its user may be in distress. If that is the case, the NEO not only goes into alarm locally on the instrument, but also remotely, over a wireless network, to notify people in the vicinity, as well as remote safety officers at a command center, that a person is down, so that help can be dispatched quickly.
