ABSTRACT:
A portable inexpensive manometer is realized by forming a housing assembly of two pivotable panels. The probe and a major portion of the tube are stored within the interior of the housing until the manometer is to be used. The measuring liquid is stored in a reservoir which is mounted adjacent a measuring gauge formed as an integral part of one of the panels. The reservoir is adjustable to obtain a zero reading prior to a measurement. The reservoir is exposed to the ambient during measurement by selective manipulation of a reservoir cap assembly.
