Hey guys, does anyone have any suggestions regarding the first look sensor compared to the Fluke sensor I assume that they do the exact same thing? . Thanks, Doug
Sorry sir, but that's a tough comparison to make. Different tools for different jobs. A PV350 will be decent for in-cylinder testing and basic pressure/vacuum testing. An FLS will be excellent for intake/exhaust/crankcase pressure pulse testing, and nothing else. An FLS will not do in-cylinder testing, and a PV-350 isn't sensitive enough for pressure pulse testing.
Both can be used for testing mechanical and breathing issues, just in different ways. The Pico WPS500 is the only probe I know that does a decent job at both.
As above the Fluke behaves like a pressure gauge, the Firstlook is a pulse sensor it behaves more like a microphone the output shows only rapid changes. The Fluke will do the in-cylinder pressure testing but I have seen a few posts in various places on the internet that show the output of the Fluke lacks resolution (fine detail) for the in-cylinder range.
The obvious alternative is the Pico but AutoDitex also make one which IN THE uk sells for around £280/350$ US
AutoDitex In-Cylinder Pressure Sensor
I made my own it is actually fairly easy to make your own in-cylinder pressure tester, all that is required is a low cost pressure sensor off eBay and a 5v power supply. The sensor is just a 3 wire industrial pressure sensor from ebay and power supply is just a tiny voltage converter called a uBec designed for drones the total cost for the electrical parts is less than £25 or 30$ US.
There are also cheaper alternatives to the FirstLook Initially I made my own to experiment with but now use an AutoDitex
AutoDitex Pressure Pulse Sensor
Which where I am in UK current cost under £60 which is about 80$ US
