True Spot Smoke Tester

True Spot® Smoke Tester

Accurate smoke readings in less than one minute
  • Quickly checks smoke level in flue gases
  • Can save combustion equipment and electronic analyzers from soot damage


The True Spot® smoke test method has long been recognized as the accepted standard for oil burner smoke tests. Testing the smoke content of flue 
gases takes less than one minute and is easily determined using the smoke scale included with the instrument.
The True Spot® is an indispensable part of any oil burner service job. High smoke levels can cause premature failure in the combustion appliance/
equipment, can damage relatively expensive electronic combustion analyzers, and can indicate excessive fuel usage.
