Sistema portátil de detección de metano/NMHC EXPEC-3200

The EXPEC-3200 (Model: 115Pro) Portable THC/CH₄/NMHC Analyzer is equipped with a color touch screen and supports hot-swappable batteries. When paired with a water-based hydrogen generator, it enables long-term hydrogen supply. The instrument delivers high measurement accuracy, long battery life, and user-friendly operation, making it ideal for on-site determination of total hydrocarbons (THC), methane (CH₄), and non-methane hydrocarbons (NMHC) in both stationary and fugitive emission sources.
