MPA mPower Electronics NEO Photo-ionization Detectors MP181 MP182  MP184  MP185 MP186


The NEO is one of the most advanced handheld VOC (Volatile Organic Compound) monitors available for ppb
(parts per billion) detection. VOCs include a variety of chemicals such as benzene, alcohols, fuels, paint thinners,
industrial solvents and many others, which can have short and long-term adverse health effects. Measuring these
compounds is essential for worker protection in industries like oil & gas, fire & hazmat, pharmaceuticals, paints &
adhesives, and many others. In addition, VOC monitoring is useful chemical process control, detecting leaks and
other releases to the environment, and in measuring indoor air quality. 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). Novel designs of the Photo-ionization Detector (PID) and Ultraviolet (UV) lamp provide outstanding
sensitivity, stability and reproducibility. Options include real-time data monitoring with a built-in wireless modem
using mPower Suite application software.
