What equipment to use when conducting a stack test?

Emissions analysers from testo are used by Ektimo to deliver stack
testing consultation services to manufacturing, energy and mining companies
throughout Australia. Stack testing involves measuring gas concentrations in
industrial emissions, ensuring organisations are adhering to regulations
developed by the Environmental Protection Authority (EPA).

Ektimo’s stack testers use testo’s emissions analysers to
quickly measure emissions concentrations at various industrial facilities. According
to Ektimo CEO Matthew Heskin, stack testing involves taking air samples out of
the ports of industrial chimney stacks to help companies meet EPA compliance requirements.
Companies and organisations across different sectors have environmental
licences, which stipulate that licence holders must adhere to specific
emissions standards.

Stack tests are conducted at regular intervals on a quarterly, annual
and bi-annual basis to detect nitrogen oxides, sulphur oxides, carbon monoxide
and particulates as well as chlorides, BOCs and metals.

According to Mr Heskin, Ektimo serves about 500 clients across Australia,
mainly covering the energy, manufacturing and mining sectors. Any company with burning
or combustion operations can approach Ektimo for stack testing consultation. Wastewater
treatment plants can also use Ektimo’s services to measure odour, H2S and other

Ektimo is accredited by the National Association of Testing Authorities

For performing a stack/emissions competence audit, Ektimo uses a
combination of portable gas analysers and wet chemistry techniques
with the equipment selected based on the location, the purpose of the audit and
the type of tests needed to be conducted. Mr Heskin says an analyser helps them
get an instantaneous measurement of the gases within the sample, simplifying
the process.

Ektimo mainly uses the testo 350, one of the most popular emissions
measuring instruments in the market for industrial applications with the
ability to measure multiple gases. The company uses testo 350 portable
analysers on almost every stack testing job, not only to test for combustion
gases but also to measure oxygen or CO2 content.

Mr Heskin explained that testo devices were superior to other
instruments because of their portability and battery operation. The battery-operated
testing instruments allow Ektimo to conduct tests at locations without power. testo’s
on-board data logger is also a great feature not available in many of the
alternative models.
