Know what your instrument can prove.

Which question matches the task?

Start with the question that matches the task: interpreting a reading, establishing instrument capability or checking a connection. Use the exact model and actual measurement conditions when following a reference. Each page keeps its sources and unresolved questions alongside the claim, so a general explanation is not mistaken for a verified result on your equipment.

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.

Elitech 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.

How should these references be used?

Identify the quantity, connection and required decision before selecting a tool. Current manufacturer instructions govern the exact equipment. Use the official guidance applicable to Great Britain or Northern Ireland. Overseas technical explanations do not establish UK legal requirements for the activity or equipment being assessed.
