Air Monitoring Industrial Emissions Analyser Simultaneously


Measures CO, CO2, H2O and O2 in Real Time A new instrument from Los Gatos Research (LGR) (USA), enables comprehensive monitoring of industrial combustion processes for greenhouse gas (GHG) emissions


compliance and other purposes. Specifically, the Industrial Emissions Analyser (CO, CO2, H2O, O2) can precisely and simultaneously measure all key combustion products (carbon monoxide, carbon dioxide, water vapour and oxygen). This product launch follows the EPA’s release of the first comprehensive survey of GHGs emitted from major industrial facilities in the U.S.


The new Industrial Emissions Analyser (CO, CO2, H2O, O2), or IEA, measures each gas independently with practically zero crosstalk (or cross sensitivity) between the four components, or with other trace gases, such as unburned hydrocarbons. The IEA also features rugged packaging, automated operation, and Ethernet connectivity which


make it ideal for portable operation as well as remote, unmanned operation over extended periods in inaccessible locations and/or challenging operating conditions.


Two models are currently offered: a Standard model with total uncertainty less than 1%, and an Enhanced Performance (EP) version with total uncertainty less than 0.03% of measured mole fractions over the entire range of operating temperatures from 0 to 45 °C.


The IEA accurately corrects for water vapour dilution and spectroscopic effects and thus directly reports CO, CO2 and O2 on a dry mole basis without drying or other treatment of the emissions gas mixture. This is unlike older conventional technologies (including


photoacoustic, FTIR, NDIR, GC), which cannot deliver these measurements without sample pretreatment. This new Industrial Emissions


Analyser (CO, CO2, H2O, O2) also delivers much higher dynamic range for all four gases as compared to any other real-time measurement technology, so sample concentration or dilution is not required.


Reader Reply Card No. 52 Automatic Weather Stations to be Installed in Indonesia


Working in conjunction with distributor, PT Inter Pasific Cemerlang, workplace and climate monitoring specialist, Casella Monitor (UK), has won an order for 14 Agricultural Automatic Weather Stations (AAWS) from the Bureau of Meteorology Climatology and Geophysics in Indonesia.


The AAWS units, which are funded directly by the Indonesian government, will be installed by the distributor in locations on Sumatra, Kalimantan, Sulawesi, Java and the Sumbawa islands in order to better understand the affect of the climate on the country’s agriculture and to improve its agricultural output.


The long term goal of the Bureau of Meteorology Climatology and Geophysics, also known as Badan Meteorologi Klimatologi dan Geofisika, is to install around 500 AAWS throughout Indonesia.


All the stations will send continuous data in one-minute bursts to the main server located in the Bureau’s head office in Jakarta. This new station network will also be linked to existing AAWS units, with the data being accessible online through a website.


Wind speed, wind direction, relative humidity, temperature, rainfall, photosynthetically active radiation (PAR), grass temperature, soil moisture, soil temperature and evaporation will all be among the elements measured by the units, with addition of a number of 10 metre high masts.


Peter Lawson International Sales Manager at Casella, comments: “This is an exciting project for us which, if all goes well, will lead to future installations of our product throughout South East Asia.”

An Official from the Bureau says: “Casella has an excellent reputation in the market for providing durable products that provide accurate information but require little maintenance.”


He continues: “Climate change has made it increasingly necessary for us to gather environmental data, particularly in respect to assisting our farmers and we hope that it will provide increased insurance for the country’s crops for years to come.”


Reader Reply Card No. Monitoring Technology for Maltese Temples Project


Heritage Malta has installed Envirologger (UK) monitoring technology at ten locations around the site of the Tarxien Temples – a highly important archaeological site dating back to between 3600 and 1500 BC.


The monitoring stations were installed in 2011 and are being utilised for research purposes and to gain reliable data for scientists, conservators and engineers to ensure the best possible management of the site. Explaining the benefits of continuous environmental monitoring, Curator Joanne Mallia from Heritage Malta says: "Naturally, the materials and structures at this site are affected by the environment, so a protective shelter has been proposed to slow down the rate of deterioration of the stone surfaces and the monitoring equipment will help create an accurate picture of the environmental conditions on site, both before and after the installation of the shelter."


The Envirologger is a highly sophisticated battery powered data collection technology that is able to accept inputs from a wide variety of sensors and output via almost any communications technology. At Tarxien, the Envirologgers are connected to sensors for measuring wind speed, wind direction, air temperature, ambient humidity, atmospheric pressure, soil temperature and wetness, and water level.


Data is transmitted to a central web logger by the new Envirologger wireless sensor nodes. The data is then ‘pushed’ to Heritage Malta. The entire monitoring and data transmission network is run on low voltage solar power because it is not possible to run cables around the site for fear of negative effects on the ancient stone structures.


The Tarxien Temples site is a recipient of European funds under the ERDF 2007-2013 programme and the installation of an environmental monitoring system will help to protect the site for the benefit of future generations.
