C&m Consulting Engineers
Research in Pretoria

Our existing suppliers, in a never ending process of research and development, have also been providing us with newer ranges of equipment, allowing us access to applications hardly ever thought of before.
We specialise in the measurement of air pollutants both at the source, through manual source emission measurements and continuous emission monitoring, and at ambient air quality levels through ambient air quality monitoring.
We would also like to make use of this opportunity to thank all involved, especially Mr. Samuel Kapesa and and all ECZ representatives for their hospitality and help during the installation.

We specialise in the measurement of air pollutants both at the source, through manual source emission measurements and continuous emission monitoring, and at ambient air quality levels through ambient air quality monitoring. C & M supplies, installs and maintains equipment for the monitoring of air pollution. All ancillary equipment associated with the above are also supplied and installed by us. C & M has a fully functional emission sampling team, specialising in the sampling of particulate and gaseous emissions at both source and ambient levels. All source sampling is done in accordance with accepted national and international standards, including USEPA, EU, ISO, NIOSH, OSHA etc. Our consulting services include dispersion modelling, developing design information and selection of gas cleaning equipment, training in sampling methods, data reduction, validation and reporting. We have also recently expanded into air quality management plans and emissions inventories. In addition to supplying equipment, C & M also provides a wide range of services to various clients. Plans are underfoot to train additional staff to offer faster reaction times to calibration queries. We undertake source emission measurements, both standard and specialised. With our engineering background, we are able to generate design data for air pollution control equipment. We are also able to provide an initial selection of the most appropriate types of control equipment required to reduce emissions into the atmosphere. Our sampling activities include both isokinetic and gas sampling. Isokinetic sampling activities We make extensive use of USEPA sampling methods, although the basic basic isokinetic sampling procedure we use meets the requirements of USEPA Method 17 and ISO By adapting the sampling train, we are capable of sampling both particulates and gases simultaneously where required. We work with various laboratories to ensure that sample integrity and chain of custody is maintained at all times. Sampling is performed by C & M, and the samples are analysed by a suitably qualified and accredited laboratory. Gas analysis activities In addition to isokinetic sampling, we are also capable of doing gas analysis, mainly in accordance with USEPA methods. As with isokinetic samples, we work with various laboratories to ensure that sample integrity and chain of custody is maintained. In addition to the above activities, we also provide a wide variety of additional services to our clients. Training in operation and maintenance of monitoring equipment and related software.
