Thermometers & pressure gauges

Gauges show at a glance whether the heating is working properly: a thermometer shows water temperature, a pressure gauge the pressure of the closed circuit, and a thermo-manometer both in one instrument. A drop in pressure, for example, points to a leak or a problem with the expansion vessel.

You will find FIMET and CM ITALY instruments with back or bottom connection, remote immersion thermometers and sensor pockets, which let a sensor be fitted without draining the circuit. Before buying, check the connection position, the thread and the scale of the gauge.
