The documentation level and original check dates above are retained. Listing a source does not mean every linked manual or report was read, nor that Hydrogenology verified supplier test claims.

Only email-confirmed, moderator-approved ratings contribute. Email verification does not verify ownership or prove performance/safety. Comments may be submitted without a rating.

This uses the existing verified-request system. Exact aliases are reconciled with historical requests; one verified email counts once per model.
Before interpreting a specification
Source output, gas purity, mixed-gas composition and actual inspired exposure are different. Generator production of H₂ and O₂ alone does not establish their coadministration.
