AdBlue Refractometer :: Urea Concentration Testing

The AdBlue refractometer is a new hand held sensor developed to address the growing need to check the urea concentration in AdBlue.

Escalating urea prices have driven the cost of operating an SCR higher than ever before. Regretfully this has led to a new wave of problems where supplies of diluted AdBlue have found their way in to the market.

Often rebranded ‘Automotive urea solution’ to eliminate the risk of prosecution by trading standards (as a mix of less than 31.8% urea cannot be labelled AdBlue). Victims of this weaker concentration may not be able to seek compensation under the Trades Description Act.

Tell tale signs of whether you are victim of a diluted supply include vehicle consumption rates regularly exceeding those quoted by the manufacturer. This is because the vehicle, if fitted with a NOx sensor, will inject larger volumes of the weak solution in an effort to reduce the emissions adequately.
