Pressure Transducer
A PicoScope can be much more than an electrical diagnostic tool. Add the high speed WPS500X Pressure Transducer that measures pressures up to 34bar (500psi) and reacts in one ten-thousandth of a second. It can also be used to measure vacuum and is compatible with air, coolant, petrol, diesel and lubricant oil.
With the unparalleled speed, resolution and accuracy of the WPS500X Automotive Pressure Transducer you can perform quick and accurate analysis of many automotive systems.
Download both the WPS500X Brochure and the User’s Guide.

Compression Testing Example
A compression gauge measures peak pressure. All low pressure information – that can show timing errors and other subtle faults – is hidden. For example, see the ripples between BDC Expansion and TDC. That is caused by turbulence in the air rushing past the exhaust valve.

How it works
Our WPS500X kits have hoses and adaptors that allow you to connect to fuel and vacuum systems. The kits include spark plug adapters and glow plug adapters are also available for diesel compression testing. There are three ranges:
- 1: -1 to 34.47 bar (e.g. Compression Tests)
- 2: -1 to 3.45 bar (Vacuum and Fuel System Tests)
- 3: -0.34 to 0.34 bar (Exhaust gas pulsations)
Please visit the WPS500X page for guided tests, videos and lots more information. Also see our page on WPX500X Kits. Here is a list of some example tests:
