About Us

Watertest Systems Pty Ltd, the company behind testkits.com.au is a manufacturer, importer and supplier of test kits and reagents. Our head office is based in South-West Sydney Australia, from here we supply our kits to several countries all over the world. We have supplied our products and services  to many industrial  and environmental  laboratories and large testing companies for over 20 years.  Our products are used widely in Australia, New Zealand, PNG and in the Asia Pacific region.

This site is dedicated to people who do not have access to a municipal water supply and are reliant on tank water, bore water or river water as their primary source of domestic and potable (drinking) water.  The aim of this site is to be a source of information, products and service that will enable people to carry out their own testing and have an appreciation of what the results mean.

This site is not intended to be the complete "package".  We would encourage people to do their own research, followed by routine water testing and then to work with your local water authority, local government offices, and/or a NATA registered testing facility.  Combined, all of this information should come pretty close to being the complete "package" for a specific location.

The motivation for this site was that we could not find a single source of products, services or information on drinking water testing or standards anywhere.  Hopefully this site will fill the gap.

The products being offered on this site have been sourced from a variety of different suppliers across the world.  We have tried to select simple non technical products which have been designed specifically for drinking water applications.  We were unable to find what we considered to be the complete range of products from any one supplier.  We have selected these products as they meet our criteria of offering accurate and repeatable results, are simple to use and are what we consider to represent good value.

We are offering what we believed is a complete range of products for household use.  We are not trying to turn you into Chemists or take the place of testing laboratories.  We are just trying to give you the tools to inexpensively carry out some basic testing.  If you do or do not agree that we have met our goal or you want us to add to our range please make use of our forum, we are looking forward to your feedback.

Please contact us on the details below, via "testkits" on Facebook or through the forum for any help and assistance you may require with your water testing needs.
