Top Ten Air and Water Monitoring Companies Had A 20 Percent Market Share Last Year

The top ten companies in the air and water monitoring market had 2013 revenues of $4.7 billion representing 20 percent of the $23 billion market. This ranking analysis has just been posted to the McIlvaine report, Air & Water Pollution Monitoring World Markets.

The market share is down slightly from a similar analysis last year. This is in part due to the growth of Asian suppliers.

Top   Ten Air and Water Monitoring Companies





Endress +   Hauser


Thermo Fisher










Mettler Toledo






There are many thousands of companies participating in this market with sales of less than $100 million. The total market includes those companies providing periodic sampling. They often consist of a handful of people with a modest investment in portable test equipment.

At the other end of the spectrum is Emerson which has complete automation systems for air and water monitoring and control. It is also a major supplier of combustion analyzers including oxygen and carbon monoxide. The forecasts include distributed control systems and PLCs used in the monitoring process. For this reason the top ten list includes not only Emerson but Yokogawa, Siemens, Invensys and ABB.

Endress + Hauser and Thermo Fisher have the widest assortment of instruments, but they are not at the top of the rankings because they do not supply extensive software.

The automotive test system portion for Horiba is included because it is centered on measuring the impurities in the gas discharged from engines. This is a substantial portion of Horiba sales and, thus, elevates the company to the top ten rankings.

There are several segments of the market growing at double-digit rates.  One is the market for continuous emission monitoring systems for gas turbines. Another is the monitoring of shale gas and oil extraction and processing. The highest rate of growth is for continuous emissions monitoring systems for coal-fired boilers in China. Much of these revenues are captured by Chinese companies even though the instruments are purchased internationally. This growth has been another factor in the slight market share decline by the largest companies.
