Seal leak displacement comparator

Separate gas-volume collection and time/pressure/temperature comparison hardware for near-ambient witness leakage. Collection background/backpressure unqualified.

Discovered · unresearchedClosure: OpenInventory incomplete

Capability requirements and tolerances

Consumer-specific numerical targets, quantities and acceptance limits remain open or incompletely reviewed. No smartphone-grade suitability is claimed. Distinct capability tiers require their own making route and qualification.

Making outline

Mount a separate rigid inverted metal bell in an open overflow-water bath, deliver collected gas through a submerged dip tube, and weigh displaced water over independent timed intervals with temperature/backpressure/background comparison
Detailed procedure and acceptance remain unresearched.

What remains unresolved

Manufacture, quantities, suitability and complete inventory remain unreviewed.
Current memory-first method needs source and compatibility review.
