Thermometers and manometers

Thermometers and manometers monitor operating temperature and system pressure at key points in a burner or boiler installation. A thermometer is typically fitted on the flow or return pipe to confirm that the heat exchanger is working within its design range, while a manometer reads circuit or combustion-air pressure and is often mounted on the appliance casing or pipework tee.

Choosing the correct gauge depends on the measurement range, dial diameter, connection thread, and — for capillary types — the probe length and immersion depth. Connection angle (straight or angled) and the position of the scale on the dial also affect fitment. Parts from ACV, De Dietrich and Kromschroder are represented in this section. If you have an order number from the original manufacturer, use it to match the replacement directly; model designation or appliance type will narrow the search when only those are available.
