Built Oz DIY Wideband Units

Oz DIY Wideband Meter

All prices shown are in AU dollars. Please see the note below regarding exact AUstralian dollar and approximate US dollar pricing.

Soon we will offering the Oz DIY-WB unit, its matching 5301 wideband display and the WB to sensor cable in fully built and tested form. Why? Because we recognise many people just don't have the time to build the unit from the kit of parts.

We will be offering new models with extra features in the future, but the current Oz DIY-WB may just be the cheapest and best performing true wide band AFR/Lambda meter on the market today.

Here's some more information on the DIY-WB and the WB unit's Lambda & AFR specifications. We also have information on the NTK L1H1 sensor the WB unit requires.

You can purchase the built and tested Oz DIY-WB as individual components comprising:

  • built and tested Oz DIY-WB unit @ AU$200.

  • 2.6 m sensor cable, @ AU$80 (add AU$20 for 4.5 m).

  • 5301 display @ AU$200 (optional RS232 @ AU$20).

There's also a package of Oz DIY-WB unit, 2.6 m cable and 5301 display (with RS232) at the discounted price of AU$480 (save AU$20). Approx. US$269 order it here.

You can ORDER THEM from us at Tech Edge.

Prices, Ordering, Insurance, Shipping, & GST

Prices noted here are shown approximately in US dollars, and shown exactly in AUstralian dollars (excluding GST). The Australian price is firm and we show the approximate derived US price based on a conversion rate of $0.55 US cents to an Australian dollar.

If you purchase using a card then we can only bill you in AUstralian dollars and your card provider will convert to your local currency on your statement using the rate they determine at the time of conversion (they may also charge a small conversion fee too).

If you purchase using PayPal then we will charge an additional 3% over the US dollar prices shown here to cover the unfavourable exchange rate that PayPal gives us when we necessarily covert back to AU dollars.

We will add shipping and insurance (if required) when you place your order. We suggest you insure your goods if they have a value of over AU$100. Note that we cannot insure to some some destinations. If you ship back an unassembled kit for construction you should ensure it is adequately packaged and (if you wish) insured.

All Australian orders will attract the 10% GST on the total of the order.
