Wobbe Index / Btu
WIM 9610


Precisive 5 - All Optical Hydrocarbon Analyser


Using a unique wavelength-sweeping tunable filter spectrometer, fast update rates down to sub-second intervals are performed for the full C1 through C5 analysis and C6+ to calculate Heating Value / Wobbe Index.

The analyzer does not require carrier gas, fuel gases, or on-site calibration gases.




WIM 9610 - Wobbe Index, BTU Calorimeter


The New COSA 9610™ is the latest instrument from COSA Xentaur for measuring Wobbe Index, BTU/Heating Value and CARI (Combustion Air Requirement Index).



PRO Portable Calorific Value Measurement


one of the first commercially available portable Optical Gas Calorimeters. After extensive development work, this instrument proudest the fastest spot check response in the industry; T90=15 seconds for Natural Gas and LPG


Wobbe Index / Btu / Caloric Value Analysis

Combustible Gas Analyser


What Is The Wobbe Index?

The Wobbe Index is actually the correct representation of the heating value of natural gas arriving, from the gas line, at the orifice where a burner is located.

It is not simply the BTU per cubic foot but rather the BTU per cubic foot divided by the square root of the specific gravity.
