728A 1-1000 Torr, Heated (100°C) General Purpose Absolute Baratron® Capacitance Manometers
Overview
The 728A 1-1000 Torr, Heated (100°C) General Purpose Absolute Baratron® Capacitance Manometers blend of small size, up to 100 C operating temperature, 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.
- Smallest Baratron® heated vacuum gauge available, easily mounts inside process systems and gas cabinets
- Operating temperature of 100°C prevents deposition of process gases and by-products that cause drift
- Analog output of 0-10VDC interfaces with most control systems
