NEO Photo-ionization Detectors

Professional gas detection and alarm systems

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 15,000 ppm for different applications and a benzene-specific version (NEO BENZ). A novel design of Photo-ionization Detector (PID) and Ultraviolet (UV) lamp reduces interferences due to humidity. Options include real-time data monitoring with a built-in wireless modem using mPower Suite application software.
