The Digital Vacuum Gauge is an accurate replacement for old dial vacuum gauges. The large easy-to-read 3-digit display includes a bar-graph Liner Wear indicator which warns when liners need changing. Specifically-designed to replace dial gauges, the measurement system includes special damping to prevent digit ‘bounce’ during small vacuum instabilities but still responds to large vacuum drops. Includes a ‘Fast’ mode for technician use during regulator adjustment. Uses InnovAg’s digital calibration system with no manual adjustments for excellent long-term accuracy.
