Air and Water Instrumentation Market to Exceed $14.1 Billion This Year


Expenditures for portable, laboratory and continuous measuring instruments for air and water will exceed $14.1 billion this year. This is the forecast made by McIlvaine in its Air and Water Monitoring publications. (www.mcilvainecompany.com) The definition of the market is based on the McIlvaine concept of “decisive classification” rather than scientific or literal classification. Some process analysers, software and transmitters are included in the forecast because this is the way many of the suppliers view the market and, most importantly, the segmentation which purchasers use to sort through the alternatives.

Oxygen measurement is one of the largest segments in the air and gas sector. It is used for control and safety in combustion applications. It is also used for inerting systems and gas storage. It is used to


determine the quality of CO2 used in brewing. It is one of a number of parameters measured with air pollution continuous emission monitor systems.


Dissolved oxygen measurements in water are a major water segment with analyser revenues approaching $200 million/yr. Continuous monitors are needed in beverage, aquaculture and remediation. Accurate pH, O2, conductivity and turbidity measurements are critical in modern

One of the fastest growing segments is continuous monitors for oil and gas. Water quality instrumentation is needed to monitor aquifers and surface water in proximity to shale gas operations. Gas chromatographs can continuously measure natural gas Btu content, an important parameter in energy transactions.


The total process control and instrumentation market exceeds $70 billion worldwide. The measurement and control of gases and liquid processes is just a small portion of the total, but it is difficult to completely compartmentalise this portion. The oil and gas and chemical sector listed above accounts for more than $15 billion in process instrumentation purchases including the following segments:

New Low-Cost Humidity and Temperature Sensor for High Production Volumes


Sensirion (Switzerland), manufacturer of humidity and temperature sensors, is presenting the SHT20 humidity and temperature sensor at this year’s Sensor+Test trade fair. The SHT20 is a low-cost member of the SHT2x family of sensors, which are already being used in the millions in various applications. With a typical accuracy of 3% RH, the new sensor is especially suitable for price-sensitive applications and shows that high production volumes can be combined with low cost and proven quality.


The SHT20 humidity and temperature sensor boasts the same impressive features as the standard version. It is distinguished by high long-term stability, full calibration and both digital and analog interfaces. The sensor is based on the unique CMOSens technology, which enables high production volumes with excellent value for money. The minimum order quantity is 1,500. Despite being significantly less costly than its predecessor, depending on purchase volume, the sensor offers excellent temperature measurement accuracy of ±0.4 °C and a measuring range of -40 to +120 °C. With a 3x3-mm footprint and 1.1-mm profile, it is one of the smallest sensors in its class. These properties make it the first choice for many applications.

Sampling Bags for Collecting Air Samples Prior to GC and GC/MS Analysis


Sampling bags are widely used as a convenient method for collecting air samples in such applications as automobile interior and exhaust emissions, work environments, building materials, textiles, soil gases and odours/aromas prior to GC and GC/MS analysis. GL Sciences have now launched a new range of ‘Smart Bag’ sampling bags which have been developed to meet the needs of analysts in a wide range of fields. A range of 7 bag materials is available, allowing the composition of the target compounds in the sample to be optimised for a particular application. Additionally Smart Bags can be supplied in an extensive range of shapes, sizes and connector configurations. For further information and a technical brochure on Smart Bags, contact Hichrom Limited (UK).
