A pressure measuring apparatus especially of aggressive fluids includes a manometer whose casing accommodates a diaphragm separating a first chamber within the casing from a second chamber within the casing. The first chamber contains a neutral fluid which transfers the pressure of the aggressive fluid provided in the second chamber and exerting a pressure onto the diaphragm to a mechanical indicator of the manometer for indicating the measured pressure.
