GAWIDG25P-005-4L, Weiss Instruments,

The Weiss Series DG Gauges are used where accuracy is required in the measurement of pressures below 10 psi. This line of diaphragm gauges offers an instrument highly sensitive yet durably constructed. Utilizing a thin walled copperalloy, the diaphragm senses slight pressure or vacuum and expands or contracts. The action of the element is quickly and accurately indicated within 1.5% of full scale range. The Weiss Diaphragm Gauge is an excellent choice for a wide variety of applications where the standard bourdon tube gauge cannot perform reliably. Some of the uses are filter monitoring, leak testers and LP gas.
