728A 1-1000 Torr, Heated (100°C) General Purpose Absolute Baratron® Capacitance Manometers
Model: 728A

Overview
Overview
The 728A 1-1000 Torr, Heated (100°C) General Purpose Absolute Baratron® Capacitance Manometers blend of small size, high operating temperatures, rugged corrosion-resistant Inconel® sensor, and performance make this heated capacitance diaphragm gauge an ideal solution for new process equipment and retrofits into existing process tools. The 728 Baratron® manometer is heated to 100°C, and uses a robust sensor design that provides high tolerance to overpressure, and its all-Inconel construction gives exceptionally high corrosion resistance to process gases and by-products found in many applications.
