Soot / Particulates

Why Use a Smoke Test Pump?

A smoke test pump supports practical checks when setting up an oil burner, checking an oil boiler after servicing or assessing the effect of a burner adjustment. During an oil burner smoke test, the resulting soot or smoke number shows how much soot was present in the sampled flue gas at the time of testing.

The same principle applies during an oil boiler smoke test. The reading gives you a repeatable way to compare soot levels after servicing or adjustment without relying only on the visible appearance of the flue gas. Used for a suitable burner, the result provides useful information when reviewing combustion performance.

Manual soot testing performs a different role from a Flue Gas Analyser. The manual test produces a soot or smoke number from a filter-paper mark, while a flue gas analyser provides gas and temperature readings supported by the instrument. These results may be considered together where the work requires more than one type of combustion reading.

How Does a Smoke Test Pump Work?

The pump draws a measured flue gas sample through filter paper. Soot carried in the sample collects on the paper and forms a visible mark. You compare that mark with the appropriate soot or smoke scale to determine the soot number or smoke number.

The filter paper, sampling equipment and comparison scale must all suit the intended test because each forms part of the measurement method. A smoke tester for oil burners should therefore be selected with the correct test components for the intended burner and fuel rather than treated as a general-purpose gas instrument.

An oil smoke test pump provides a simple manual measurement rather than an electronic concentration reading. It suits work that specifically requires a soot or smoke-number result from a suitable liquid-fuel burner. The principle is straightforward, but the equipment and consumables still need to match the intended application.

What Is a Suspended Particulate Analyser Used For?

Suspended particulate matter consists of small solid particles carried in flue gas. For suitable solid-fuel appliances, an electronic suspended-particulate analyser measures the concentration of those particles rather than producing a soot number from filter paper.

Selected equipment may also provide related combustion readings such as oxygen, carbon monoxide and flue temperature where supported. These functions give you additional recorded values, but the available readings depend on the instrument rather than applying to every analyser.

Particulate concentration and a manual soot or smoke number are not interchangeable results. One measures suspended particles electronically, while the other compares a filter-paper mark with a reference scale. Our Measuring Instruments selection supports different testing requirements, so the required reading should guide your choice before ordering.

How Do You Choose the Right Testing Equipment?

Start with the fuel and the result you need. For a suitable oil or other liquid-fuel burner, manual soot testing suits work that requires a soot or smoke-number reading. For a suitable solid-fuel appliance, electronic particulate measurement is the relevant method when you need a particulate-concentration result.

The test requirement matters just as much as the fuel. A smoke test pump uses filter paper and a comparison scale, while an electronic particulate analyser records concentration electronically. Choosing between them therefore depends on the measurement required, not simply on which instrument provides more readings.

For manual testing, check that the supplied sampling components, hose, filter paper and comparison scale suit the intended work. Portability also matters when equipment needs to move between sites or plant rooms. For electronic testing, consider the supplied probe, recording functions and other supported readings where these features matter to your work.

If you regularly test oil-fired equipment, manual soot testing provides the direct soot-number result needed for suitable burner checks. If your work involves suitable solid-fuel appliances, an electronic analyser is designed for particulate concentration instead. We can help you compare these methods without treating one as a substitute for the other.
