Wireless electronic engine pressure indicator

The ELPI is the most accessible Electronic Engine Pressure Indicator on the market. Our patented technology delivers faster results and easier readouts.



Watch our video demonstration to see just how quick and easy it is to analyse engine performance using ELPI.

The ELPI provides users with the following benefits:
  • Affordable price coupled with high performance and reliability.
  • Remotely controlled operation facility.
  • Utilises the same mini-computer as the engine crankshaft deflection device, EDD.
  • Compact and easy to store.
  • User-friendly design.
  • Pressure graph readings on a 30 engine-cycle basis.

The memory stores data for as many engines and cylinders as you require. All data can be transferred to a PC or transmitted ashore for evaluation and archiving. The ELPI saves you time and expense, whilst offering accurate measurements in the shortest times possible.
