1. A manifold gauge assembly for use on a fluid system, for example an HVAC-R system, the manifold gauge assembly comprising:
a manifold for connection to the fluid system,
a pressure gauge arranged to detect a fluid pressure in the manifold, the pressure gauge comprising a display to display a detected pressure,
an electronic pressure sensor arranged to detect a pressure between the manifold and the pressure gauge, and
a communications unit arranged to receive data from the electronic pressure sensor and to communicate with a remote device,
wherein the electronic pressure sensor is disposed between the manifold and the pressure gauge, and
wherein the manifold gauge assembly comprises a connecting tube disposed between the manifold and the pressure gauge, the connecting tube comprising a connector for removably connecting the pressure gauge to the connecting tube, and wherein the electronic pressure sensor is disposed in the connecting tube.
