Model 120 Catalytic VOC Gas Analyzer
Product information
The Model 120 Catalytic VOC Gas Analyzer from HNU Instruments provides continuous measurement of a wide range of volatile organic compounds (VOCs), including methane and other hydrocarbons. With dual detection ranges (0–100 ppm and 0–20,000 ppm), a bright OLED display, onboard data logging, and optional Bluetooth connectivity, this analyzer is ideal for field and industrial use. The sensor uses catalytic oxidation at 900°C and measures differential output via a Wheatstone Bridge. Portable, rechargeable, and accurate to ±2%, the Model 120 is built for safety, reliability, and performance.
