About OdaLog®


App-Tek was founded in 1992 to source air monitoring equipment from around the world and to concentrate on supplying that equipment for Occupational Health and Safety applications within Australia.


In July 2000, to focus on research, development and manufacturing of the OdaLog® gas logger, a new wholly owned entity “App-Tek International Pty Ltd” was established.


Following market acceptance in Australia for the OdaLog® product range within the Waste Water Industry, international marketing activities commenced in 2003 with many distributors overseas been appointed due to the excellent acceptance of the OdaLog® brand in Asia, Europe and North America.
In 2007, App-Tek International Pty Ltd was acquired by Biolab Group part of Alesco Corporation Limited.


In April 2009, Thermo Fisher Scientific Ltd acquired the Biolab Group from Alesco Corporation. Thermo Fisher Scientific Inc. (NYSE: TMO) is the world leader in serving science, enabling our customers to make the world healthier, cleaner and safer.


The OdaLog® future continues to grow and develop to deliver products that are designed to survive in harsh environments for the Wastewater and other industries.
