Although I have not tried the unit in the link, I have tried several similar units, which rely on an ultrasound source for detection.

These units all failed to work in a composites environment. They do not detect the low volume sounds that are produced by vacuum leaks.

Think of it this way:

This unit is designed to detect a truck airhorn from 1 meter distance. You want a unit that can detect someone whispering from 100 meters away…

Sensitivity just does not make it.

at five pounds it does make it into the “cheap” category though :slight_smile: Most of them that i have seen start around $175. Never hurts to ask.

Can someone recommend a good one to start with please?

#5

Either the Airtech one or the Inficon one. I must admit I have both lying around, but still need to do a side-to-side test. (also have a much more expensive unit. Will it be a better unit??

I don’t suppose you want to sell me one? :wink:

I recently contacted a couple of UK companies to get a quote for the Inficon Whisper and found that it is cheaper to buy one from the US(even paying the duty) Try Ebay

Yes i noticed this too!
contacted Javac and the price from them was £213 plus 20% vat +shipping
a bit hefty for me as i’m just starting out.

I have had success using a stethascope (spelling) the thing the doc listens to your heart with.
