Elitech VGW-mini: documented capability and open questions
The VGW-mini is documented as a dedicated vacuum gauge with App recording and export features. Elitech’s product page lists segmented accuracy and resolution, plus a 1/4 SAE interface. That supports a vacuum-measurement role, but does not verify the contents of a particular UK kit, its mating fittings or our own accuracy results.
Read the reference InstrumentsElitech LMG-10: pressure and temperature, with limits
Elitech’s comparison table describes the LMG-10 as a two-valve digital manifold with pressure and temperature measurement. Its vacuum entry is ATM/101 kPa, not the dedicated micron range shown for other models. The same column marks App control unavailable. LMG-10W is a different model and its features must not be imported into this profile.
