Series 300 2-3/4" Dial for Gauge pressure For test, laboratory, and production uses, this gauge gives accuracy in a compact size. It is sensitive, yet rugged and low in cost. Available in 18 standard ranges (including vacuum and compound ranges), the Series 300 is convenient to use. Pressure is applied to the capsule through a single connection in the case. Readings are referenced to atmospheric pressure in the case.
