The CalorVal is an industrial strength assembly consisting of a heated flame cell and integrated controller that continuously measures the heating value (Calorific Value) of gaseous streams of industrial processes.

A carefully metered flame burns at a constant reference temperature inside an explosion proof measuring cell. A sample, drawn from the atmosphere to be monitored, is passed through the flame cell. A thermocouple measures changes in flame temperature. An increase in temperature is directly proportional to the heating value.

Autocalibration solenoids which allow remote activation of calibration tests are standard.
