True Spot

Smoke Test Kit
The Bacharach True Spot Smoke Test Kit determines efficient combustion and is internationally recognized as the standard
method for evaluating smoke density in the flue gases from distillate fuels. Too much smoke is one of the most common
causes of excessive fuel usage and expensive service requirements. That is precisely why the smoke test is an indispensable
part of any oil burner service job; and with the True Spot, an accurate smoke reading takes less than a minute.
The True Spot smoke test method has long been recognized as
the accepted standard for oil burner smoke tests. It is used by
Underwriters’ Laboratories in approval testing of oil burners;
and it is the test method specified in the Installation Standards of
the National Oil Fuel Institute by U.S. Department of Commerce,
Testing materials (D2156-65), and German Standard DIN 51-402.

CO Indicator Kits
Carbon Monoxide Indicator
Monoxor Detector

A quick, easy to use instrument that measures carbon
monoxide by simply drawing an air sample through a
chemical reagent in a glass indicator tube.

The Monoxor Detector is also fast and simple to operate.
An air sample is drawn through a detector tube containing
an indicating gel; if a stain forms after one pump stroke,
the CO concentration is 300 ppm or higher. If it appears
after two strokes, the concentration is 100 to 300 ppm. If
no stain appears, the concentration is less than 100 ppm.

If carbon monoxide is present, a stain appears in the
indicator tube; the length of the stain is measured against
a built-in scale to determine the CO percentage or parts
per million (ppm).
