[Instrument Introduction]
Integrated liquefied gas analyzer (three in one)It consists of a portable gas chromatograph, a high-purity hydrogen generator, and a touch screen industrial computer. The instrument can analyze gas components including liquefied natural gas (LNG), liquefied petroleum gas (LPG), compressed natural gas (CNG), and quickly provide characteristic indicators such as high calorific value, low calorific value, density, relative density, Huabai number, and combustion potential for different gases
