Diesel Testing – On-Site Service

IPU’s on-site diesel testing service is fast, economical and efficient.

We take a reliable fuel sample from your tank, we carry out analysis instantly or back in our lab and we leave you with an unambiguous picture of the condition of your fuel.

You already know that diesel testing is the essential first step to reliable power. Applications ranging from hospitals to data-centres to underground mines simply cannot afford any power outages caused by generator failure. This becomes a very real risk if your fuel is found to be contaminated and unsafe to use.

However you do not have the time or the resource to test your own fuel and would prefer to have someone else manage this. That someone is IPU.

How does IPU's on-site diesel testing service work?


  1. We respond to your enquiry promptly.
  2. A consultation process follows where a member of IPU’s customer support team contacts you to determine your exact requirements. For example, how many fuel samples do you want taken and from how many storage tanks? What is the total capacity (in litres) of your tank/s?
  3. We schedule the site visit.
  4. Our fuel technician arrives on-site and takes fuel samples from your selected tank/s. For the most accurate results possible, the engineer takes a sample from the top, middle and bottom of each tank.
  5. Analysis is either carried out instantly at your site or the samples are taken away for lab testing.
  6. Using IPU’s portable diesel analyser and a fuel sampling kit, the engineer tests your fuel samples for any potential contamination. The engineer connects the sample bottles to the portable analyser and the fuel is moved to the unit and back to the sample bottles.
  7. The portable diesel analyser reveals the condition of your stored fuel within a matter of minutes. The results are easy to interpret – ISO4406, SAE and EN590 codes are displayed on the blue screen.
  8. The data returned for each sample is stored on a USB stick.
  9. Once the diesel testing operation finishes, the engineer delivers the results.
  10. The engineer makes recommendations on-site for follow up action. If your stored fuel is found to be unsafe to use and putting your critical power at risk, a fuel clean is typically the next course of action.
