Dwyer series-7000b Series 7000B Spirahelic® Pressure Gage

Dimensional Enlargement


The Series 7100B and 7112B Spirahelic® Pressure Gages are available with an impact-resistant Turret-Style Housing which is an economical replacement for existing gages in many industrial applications. Direct drive of lightweight, precision-balanced pointer reduces friction for improved responsiveness and accuracy. The 4 ½" gage is enclosed in a rugged 5.9" (14.9 cm) diameter by 3.1" (7.9 cm) deep polycarbonate body with convenient dual-size process connection and crystal clear window. Mount gage easily in pipes or on beams and flat surfaces.
