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. The company built up a comprehensive range of scientific measurement apparatus which included sound level meters, noise dosimeters, heat stress monitors, dust samplers, and specialised air samplers to detect vapours and hazardous gases.

In 1993 the business moved to premises at Brendale in Pine Rivers Shire, Queensland, Australia and App-Tek then began to promote its imported product range into new areas. In particular, App-Tek successfully introduced the Neotronics MiniGas portable gas detector to the Australian underground coal mining industry and by the late 1990's had developed this product to the extent that it had become the most used and best supported portable gas monitor in this industry.

With the employment of key technical staff in the mid to late 1990's, the new skills they brought allowed the company to address a niche market opportunity to design an electronic measuring instrument for odor control in the wastewater industry. Ensuing research and product development culminated in the January 2000 launch of an innovative environmental product, the OdaLog H2S Gas Logger, and by this stage the business had grown to employ 15 people.

The initial OdaLog Logger (see image opposite) was designed specifically to record hydrogen sulphide gas emissions to address environmental odour control concerns associated with urban wastewater collection systems and was quickly recognised as the most advanced gas logging device available in terms of its application for sulfide odor source monitoring in the Australian wastewater industry. (Prior to the development of the OdaLog H2S Gas Logger, various H2S safety gas detectors were being modified and adapted for this application with limited success).

To address increasing market demand, floor space was increased in July 2000 and again in December 2002 through the purchase of additional premises adjacent to the existing facilities at Brendale in Queensland.

To focus on research and development and to maximise exports, a new wholly owned entity "App-Tek International Pty Ltd" was formed to employ the Research and Development team. This new business began operating from the new premises from July 2000.

The original business (now known as App-Tek Safety Pty Ltd) remained at the original address to concentrate on maintaining the existing importing business as well as to promote the first OdaLog model within Australia.

Following market acceptance in Australia, international marketing activities commenced and, as at June 2003, distributors had been appointed in twenty one countries with excellent acceptance of the OdaLog brand occurring in Europe and North America.

Concurrently with this overseas activity, staffing has grown to the present level of 14 people at App-Tek Safety and 24 people at App-Tek International.

As a result of acquiring further specialist staff and expanded Research and Development effort, enhanced monitors are being developed and it is anticipated that increasing sales will lead to around 100 people being employed worldwide at App-Tek by year 2010.

Because the three shareholders of App-Tek are all dedicated "hands on" Directors who work full-time in the business, this future expansion will continue to include valuable input from staff and customer.
