The smoke tester testo 338: flexibly applicable and suitable for industry

Whether you are technician servicing diesel engines or a manufacturer who needs to provide proof of emission values - determining the smoke count is often part of your job. With the Smoke Tester testo 338, you are equipped for the determination of the degree of blackening from diesel engines.

The easy-to-operate, handy measuring instrument records the soot concentration (mg/m3) and the Filter Smoke Number (FSN) or Bosch number for you.

Smoke tester – working with an instrument for measuring the degree of blackening

One of the soot measuring instruments also measures the degree of blackening. The handy instrument is capable of measuring the filter smoke number and the soot concentration. It is possible to take this instrument with you and thus use it at different operating locations. This special particulate matter measuring device can carry out a direct analysis.
That is particularly important in terms of ensuring you have the data to hand on site and are able to respond. It is of particular importance when it comes to controlling diesel motors. In this way, the occurrence of emissions should be avoided. Injection can also be adjusted on a diesel engine to reduce the emission of soot.
The instruments in Testo's range are also suitable for industrial use. It does not therefore matter whether the diesel engines you want to test are located in vehicles, in industrial plants or on ships. Measurement systems no longer need to be installed on site. This is a crucial cost saving.

Measurement of the smoke number – checking the performance indicators that have to be measured

Smoke count measurment

Measurement of the smoke number is an important issue, which in many cases is even linked to a performance indicator whose measurement is mandatory. This obligation primarily exists for oil heating systems which are sometimes also used in companies and in industry. Oil heating systems first have to be tested using this measurement, before the classic flue gas loss measurement. The result of the soot count makes it clear whether the system's combustion process is working properly, or if there is too much soot formation. In this case, it may be helpful to rely on a leak detector as well.

In heating engineering, a measurement of the smoke number is an important task and it is helpful here if you have a practical smoke tester to hand. You can measure the soot count with manual or semi-automatic systems. However, this is a major challenge and it has been shown that the results are not always accurate.

It is easier if you use a digital flue gas analyser. It is not just that the measurement is carried out in significantly greater detail. It also makes analysis easier. Depending on the instrument, this is either carried out directly by the system or it can be transmitted to an interface.
