Shandong Xin Zhi Heng Instrument Co., Ltd. LNG/CNG Natural Gas Analyzer All-in-One Machine

The GC-7600R fully automatic gas calorific value analyzer is mainly used to detect nitrogen, carbon dioxide, methane, ethane, propane, butane, pentane, C6 in LNG mixed with liquid LNG, and can calculate the gasification rate based on density.

The instrument operation is very simple, even personnel who have never been in contact with this instrument can learn it quickly. Insert the gas sampling bag into the instrument's 'sample inlet' port, press 'start', and the instrument runs automatically (automatic sampling, automatic analysis, automatic signal collection, no manual intervention). The test results are automatically calculated in 10 minutes.

LNG/CNG Natural Gas Analyzer All-in-One Machine Product Performance Advantages:

lFully automatic one-key start system (automatic sampling, automatic collection, automatic display of analysis results, no manual intervention), simple operation.

lThe instrument automatically adds bridge current upon startup, no manual bridge current operation required.

lAll-in-one machine (chromatographic column, detector, dedicated calorific value working software, computer, chromatographic gas source hydrogen generator) is portable, suitable for both on-site pipeline online detection and laboratory gas bag sampling analysis;

lIntegrated sealed heating, small heat dissipation ratio, higher efficiency, energy saving;

lDual-channel calorific value working software, automatically calculates the detected gas component content, high calorific value, low calorific value, density, relative density, Wobbe index, combustion potential, gasification rate, etc.;

lWorking software calculation results are based on calorific value, density, gasification rate, etc., under national standard conditions;

lBuilt-in automatic sampling pump and electric sampling valve improve the repeatability of test results;

lGas detection components: nitrogen, oxygen, carbon dioxide, methane, ethane, propane, butane, etc.;

lThe instrument can have a built-in printer (optional);

lStandard Modbus RTU transmission protocol can be adopted according to user needs;

lThe built-in generator is equipped with a non-backflow device, effectively ensuring no backflow phenomenon in the instrument. Integrated liquid storage, electrolytic hydrogen production, and oxygen discharge, low cell temperature, long service life.
