02 Sept. 2016 - New Host - Work-in-Progress

Please note: - The WBo2 (Tech Edge) website is a work in progress during early Sept. 2016. Our email addresses may not work correctly for a few days.

The shopping cart and ordering process is undergoing a major overhaul.

If you wish to order anything then I suggest you wait until Monday 05 Sept 2016, or until I change this warning page.

We apologise for this problem which was simply caused because our hosting package expired sooner than I had expected, and I didn't want to renew the contract for another 12 months because we had received such poor service from in the past.

As previously announced, Tech Edge We are taking the opportunity to move to a warmer climate at Coffs Harbour.
This move will also allow us to pursue new business opportunities both locally and internationally.
Here's where we are right now in the ACT.
Here's where we we are moving to in NSW.

We had previously stated that Coffs Harbour was so humid for several months of the year that it made it a challenge to keep precision electronic and mechanical manufacturing equipment in service during that humid period. Well, we've decided that with solar panels and air-conditioning (mainly to control humidity levels) we can justify the much nicer location roughly between Sydney and Brisbane.

In 2013 we started working on more accurate wideband and logging equipment with better connectivity. Because of the difficulty of hiring appropriate staff, we have had to put some of these tasks on-hold but in 2016/17 we hope to make lots of changes and introduce new products.

We appreciate your feedback which you can provide using the link at the bottom of most pages from this website.

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.
