Portable NDIR syngas gas analyzer CO, CO2, CH4, CnHm, O2, H2
The infrared gas composition and calorific value analyzer adopts imported NDIR non-dispersive infrared sensors, long-life electrochemical sensors and MEMS-based thermal conductivity sensors, and uses advanced digital processing technology. It can simultaneously measure the volume concentration of six gases such as CO, CO2, CH4, H2, O2, CnHm in gas and biogas online, and quickly and accurately calculate the corresponding calorific value based on the gas concentration value
Features:
-Black anodized Modern, rugged aluminium shell, light weight, small size
-Adopt imported NDIR non-spectral infrared sensor and ECD electrochemical gas sensor
-The instrument measures the volume concentration of CO, CO2, CH4, H2, 02, CnHm in the gas, and adds the over-range limit enable function
-Guaranteed measurement accuracy within the range, over-range can be measured, and measurement value reference is provided
-The calorific value is automatically calculated, and the calorific value units Kcal/m and Mj/m can be switched freely
-The internal gas interference of the instrument is automatically corrected to ensure that the measurement results are interference-free
-Measurement of CnHm concentration ensures coke oven gas, mixed gas, generator gas, Accuracy of calorific value of gas such as straw gas
-Amend interference of CnHm gas on CH4 measurement results, accurately measure CH4 concentration
-Amend interference of CO, CO2, CH on Hz measurement results, accurately measure H concentration
-Amend interference of CO and COz measurement results, accurately measure CO and COz concentration
-Changes in gas sampling flow have no effect on H2 thermal conductivity sensor measurement results
-The instrument has intelligent judgment function of user-calibrated ventilation concentration to prevent users from misoperating and causing the instrument to be unusable
-The instrument has fast detection time, and the entire detection process can be completed within one minute
-The instrument automatically samples and analyzes, which is simple to operate, fast to measure, and free of consumables compared to gas analysis such as Austrian and chromatographic analysis
-USB output
-Li-on Battery Powered
