NEO Photo-ionization Detectors


The NEO handheld VOC detector stands at the forefront of technology for monitoring volatile organic compounds (VOCs) down to parts per billion (ppb) levels. VOCs, encompassing a wide range of chemicals from benzene, alcohols, fuels, to paint thinners and industrial solvents, pose significant health risks. Monitoring these substances is crucial across various sectors including oil & gas, pharmaceuticals, paints & adhesives, for worker safety, chemical process control, leak detection, and ensuring indoor air quality.

With models ranging from 1 ppb sensitivity to high-range detection up to 15,000 ppm, the NEO caters to diverse application needs. It’s notably equipped with a benzene-specific filter tube version for targeted measurements. The device’s cutting-edge photo-ionization detector (PID) and ultraviolet (UV) lamp offer unparalleled sensitivity, stability, and accuracy across its measurement range. Additionally, its lightweight design, robust battery life (24 hours), Bluetooth connectivity, and large backlight graphic display enhance user experience.

The NEO is indispensable for leak detection and repair (LDAR), providing continuous real-time data monitoring via mPower Suite software. This capability, alongside its rugged stainless-steel housing and ease of charging, positions the NEO as an essential tool for environmental monitoring, industrial safety, and regulatory compliance.

Whether for detecting leaks, safeguarding worker health, or monitoring environmental releases, the NEO VOC detector delivers reliability, precision, and versatility, making it a pivotal asset in a myriad of applications.
