EXPEC-3200 Portable Methane/NMHC Detection System

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.

Key Features of EXPEC-3200 Portable Methane/NMHC Detection System

High Integration · Ultra Portability

The main unit (including gas cylinder and battery) weighs less than 9 kg, only 50% of the weight of similar products.
All-in-one industrial design with a reinforced carrying handle and backpack, allowing easy hand-carrying or back-mounted transport for single-operator field measurements.

Chromatogram Traceability

Displays and automatically records sample chromatograms, enabling convenient post-analysis data quality control and traceability.

Long-Lasting Operation, Reliable Gas and Power Supply

Gas Supply: Built-in zero-grade air generator module eliminates the need for external support gas; hydrogen is supplied by a water-based hydrogen generator.
Power Supply: Built-in replaceable lithium battery supports AC 220 V power or hot-swappable battery replacement, providing more than 8 hours of continuous operation.

Optional Portable Flue Gas Moisture, Temperature, Pressure, Flow, and Oxygen Analyzer

Simultaneously measures flue gas moisture content, oxygen concentration, temperature, pressure, and flow rate, with results directly comparable to emission standards.

Built-in Multipoint Calibration Curves

Multipoint correlation coefficients are integrated into the curves for easy on-site use and convenient quality control.
