Wideband Lambda/AFR (λ) controllers for diverse applications

Dec. 2012 Happy Festive Season, July 2013 (10 Years Old!)

Tech Edge started working with wideband controllers in 2002 (our first unit, the 1.0, was not our own design). Our first 100% original and fully digital controller (the 2A0) was first sold on-line July 13 2003, to a customer in Rochester NY, USA. We believe this was the worlds first fully digital wideband controller in DIY form!

In 2013 we're going to make some physical changes to the way we operate. We are moving from our present location in the ACT to northern NSW (800 km, 500 miles away). We have gone through some major changes this year and we'll probably go through more changes in 2013. My apologies in advance to those people we're going to upset because we couldn't deliver something we normally deliver overnight, or in a few days if we're sending by overseas courier. This is the unfortunate consequence of moving while trying to maintain a fully working business!. My biggest concern is that we have not been able to complete some of the projects we promised many customers - again my humble apologies.

The DIY 2Y2 has been available since November 2012. the original 2Y1 had an option for an inbuilt 4-digit display, but we could not source a vital component and could never offer this option. The 2Y2 kits have a black case (prototype shown above). It shows the LED display mounted atop the case but alternate positions are possible.

Remember the 2Y is a DIY unit. It's not for everyone, but if you have the skills to build it then you'll end up with a professional quality unit. If you can't build a DIY unit, then we offer other units starting with the 2J range (we recommend the 2J9 model which is our lowest cost ready-to-go unit.

We offer a professional quality read-to-go unit called the 2C0B - it's small, accurate, and our lowest cost pre-built unit. Use our menu bar above to discover other models and additional information.

Because we're moving, we will probably be looking for employees who either live in the Coffs Harbour area, or are prepared to move to this beautiful part of the world. Perhaps you live overseas and have been thinking of moving to Australia! Our primary employment criteria is self reliance and wanting to have control over all aspects of what we do (design, manufacture, retail/wholesale). We are small and would prefer to stay that way while offering world class products we design and manufacture ourself. If you're interested in working for us ...

Tech Edge designs, develops, manufacturers and sells a range of professional, and DIY products. This is our website devoted to our Lambda (λ or AFR) measuring instruments.

This site requires JavaScript to be active for correct display and menu operation. It also requires the latest browsers and supports Firefox 2.0+ and Opera 9+ and Safari 5+ (earlier too?) and Google Chrome
It will NOT work correctly with Netscape 7+, and other browsers that do not correctly implement CSS. It sort of runs with the broken IE8 (ie. in some silly compatibility mode). It will NOT work correctly with Internet Explorer 6 (or below) - it used to work, but we have found it too hard to maintain compatibility with both new & old IE browsers.
