For routine test, laboratory, and production uses, this gauge gives accuracy and compact size. Its mechanism is sensitive yet rugged. And it offers high accuracy at low cost. Available in ten standard ranges, the Series 300 is convenient to use. Absolute pressure is applied to the case and readout is direct, without barometric or temperature corrections. Readings are referenced to zero absolute.
