ESI Appoints New Board Members

E. S. I. Environmental Sensors Inc. ("ESI" or the "Company") (TSX VENTURE:ESV)
is pleased to announce the appointment of Stephan Radermacher and Johan Grandin
to the Board of Directors for the Company. The Company continues to execute its
new strategy with regard to board and executive management restructuring as well
as innovative market driven product development.


Stephan Radermacher brings 20 years of industrial management experience to the
Board and will act as its Chairman. A business lawyer by education with law
degrees from Germany (Munich LMU) and the U.S. (Duke), he has held various
executive officer positions in private as well as in large international public
corporations, among them ABB Power Generation, a global business with several
hundred subsidiaries. Focusing on business development and corporate
restructuring, Mr. Radermacher most recently joined an international consultancy
as Managing Partner. In 2010 he assumed the role of Board Member and Chief
Operating Officer of Avis Financial Corporation, which has recently acquired
30,000,000 common shares of ESI along with 30,000,000 share purchase warrants. 


Johan Grandin has over 20 years of experience working with public companies and
a proven track record in raising venture capital. Currently working with Element
and Associates of Vancouver, BC, a full service corporate finance company, Mr.
Grandin brings an extensive expertise in corporate financial restructuring and
capital markets to ESI. Through his past officer and director positions for
various public issuers, Mr. Grandin has learned to streamline growth initiatives
with precision. Having also worked in the field of engineering, Mr. Grandin
holds a Masters of Science degree in Business Economics and Engineering Physics.


In addition to the above changes, Ian Middleton, Nicolas Loebel and Edwin
Mitchell are voluntarily stepping down from the Board of Directors for ESI; they
will continue to provide advisory support to ESI's Board and executive
management going forward. These directors have achieved much during their terms,
both in terms of financings and product development milestones, as well as
seeing ESI through some difficult financial times. The Company is extremely
thankful for the dedication and perseverance all three of these directors have
demonstrated throughout their years of service to the Company and its
shareholders.


The new Board of Directors and executive management team look forward to
continuing with recent product development initiatives and enhancements as they
move the Company to financial and market success.
