HVAC Leak CheckTHE UK MEASUREMENT REFERENCE

Compatibility

Check the whole connection.

A matching thread is only one part of compatibility. Check the instrument, both ends, seals, accessories and software.

What is documented, and what is still open?

This register records documented interface and software information for the Elitech VGW-mini and LMG-10, together with the fields still to confirm. It is a reference for checking evidence, not a list of approved assemblies. No complete mating assembly has been physically verified, and an unknown field does not establish incompatibility.

Does an unknown field mean the parts are incompatible?

Do not substitute a retailer’s kit title for a part-level connection check. App support, firmware, end gender and seals need exact evidence. A missing field does not mean “not compatible”; it means that a compatible relationship has not yet been established.

SAE service-port adapters: check both ends

An adapter is a relationship between two identified ends. Record both nominal sizes, male or female form, sealing geometry, valve-core actuation and operating limits. “1/4 SAE” by itself is not a complete connection specification, and a physically matching thread does not prove a pressure-tight or permitted assembly.

Build an HVAC measurement toolkit around the task

Start with the measurement decision, then choose the instrument and every component needed to obtain a defensible reading. A smaller kit can be complete for a limited task; a larger wireless kit is useful only when its sensors, connections, software and records suit the job. Entry-level does not mean suitable for unsupervised refrigerant work.

Which sources support the connection register?

The two Elitech manufacturer pages support the named model specifications recorded here. The retailer parts reference illustrates why an exact accessory part number matters. These sources have different roles: a published interface label or a catalogue entry does not verify every mating component, kit revision or completed assembly.
