Portable Diagnostic Set (ELPI + EDD)



The ingenious Portable Diagnostic Set (PDS) from Akrit Engineering is the only one diagnostic set on the market that integrates both the Wireless Engine Pressure Indicator (ELPI) and Deflection Unit (EDD) into one durable device.


Our patented technology delivers

Wireless (know-how) solution (up to 10m range), no long cables are required.

Ergonomic, easy to use - fast calculation of data (approximately 5 sec). - easy to read sensor data even on the opposite side of the open crankcase

Utilises ONE industrial mini-computer (iPC) as the engine pressure indicator ELPI and the crankshaft deflection device, EDD.

Fast data collection saves the time - Engine performance measurement in less than one minute per cylinder - Engine deflection measurement in less than one minute per cylinder.

Unique (know-how) TDC finding method. It allows to calculate mean indicated pressure (Pi) and power (Ni) without sensor on the flywheel.

Compact - Total weight with for both units: 3 kg. - Case size 32 x 26 x 7 cm.


Watch our video demonstration to see how quick and simple engine performance analysis with the PDS is.

How it works
