I created this web site because I encountered things that "just worked" rather than worked well, or better, worked really well. One thing that doesn't work so well for me is finding the time to add content to this website!
I'm the CEO (ie. general "dogs-body") of Tech Edge Pty. Ltd., which host wbo2.com. We designs, manufacture, and sell wideband oxygen sensing equipment (controllers, displays, logger, etc.) We've sold to many countries all over the world. We don't advertise but rely on word-of-mouth sales. We're still in business selling this product line, which has evolved over time, since 2002. Try us if you're a "petrol head", or you need to accurately determine how much oxygen you have in a volume of gas. Our controllers work with Bosch automotive LSU sensors (and other sensor manufacturers' sensors too!) so we're good at sensing oxygen concentrations rapidly in automotive and (some) industrial environments.
