How to
Order
I am currently not taking any orders for the TetraProbe.
Unfortunately, I have not been able to overcome a problem with the TetraProbe. After about 12,000 to 15,000 sampling points the protype begins to fail to operate correctly. The sypmtom is a failure of the contacts to make an electronic closure when the probe is retracted off the piece being scanned. I have spent many hours trying to resolve this problem, the assumption being that either the contacts are building up carbon deposits due to arcing or that the problem is mechanical in nature. Since I have tested and had failures using currents as low as 10 microamps, I am leaning toward thinking this is a mechanical problem rather than carbon build-up.
