Send us a sample and photos of your tank. We'll check the concentration and quality for free, tell you what we see in your storage setup, and quote a full lab test if it needs one.
Send or drop off a sample and we test it in our warehouse. We measure the urea concentration, which should be 31.8–33.2% (32.5% nominal). We also check the colour, clarity, sediment and smell.
If the basic check or the symptoms point to something deeper, we can test a sample from your tank against the full ISO 22241 specification. The price is quoted before anything goes ahead.
It takes about three minutes. Photos of the tank help us more than anything else. Most problems start with how AdBlue® is stored, not how it was made.
AdBlue® lasts about 18 months at 25 °C or below, 12 months at 30 °C and only 6 months at 35 °C. An IBC in the Australian sun can be well past that, so a cover or shade makes a real difference.
Open lids, dirty fill points and uncovered IBCs let in dust and flies. Particles as small as a few microns can block the dosing module and injector.
Reused drums, jerry cans, watering cans and anything that once held diesel, oil or coolant. Even a trace of these can put AdBlue® out of spec.
AdBlue® attacks brass, copper, zinc (galvanised), aluminium and mild steel. Fittings made of these add metals that show up in a full test and can damage the catalyst.
Tap water or rainwater dilutes the urea and adds minerals. Only demineralised water is used to make AdBlue®, and it is never added on site.
Stock ordered in bulk and left for a year, especially outside, often reads low on concentration. Buying a size you use within a few months keeps it fresh.
A test result is only useful if something changes. Depending on what we find, we can quote on:
No. We'll check any brand from any supplier.
The urea concentration plus a visual check for colour, clarity, sediment and smell. That finds the most common problems: dilution, heat damage and dirt.
A full test is against the ISO 22241 specification. It covers urea content, alkalinity, biuret, aldehydes, insoluble matter, phosphate and trace metals. We quote it before it goes ahead.
Most off-spec AdBlue® goes wrong in storage, not at the factory. Photos show us sun exposure, open lids, dirt, insects and the dispensing gear, so our advice fits your site.
Yes. Tell us on the form or call, and we'll quote an inline AdBlue® filter to suit your pump and hose.
Use a new or clean plastic bottle, run a litre through the hose first, then fill about 500 mL and seal it. Label it with the date, where it came from and the batch number.
Before you send a sample, check the certificate you already have. Our guide shows what to look for.
Check four numbers: urea content, refractive index, biuret and sodium. Sodium is the key contamination check. It comes from dust and impurities and permanently poisons the SCR catalyst.
