Dual input manometer - Differential pressure measurement with recording and viewing of maximum, minimum, and average pressure values. This helps you monitor pressure differences over time, identify trends, and detect anomalies between two points. Digital manometer - Includes 11 air pressure units and a data retention function for easy unit conversion and historical reference. Provides flexible measurement options and keeps readings for documentation or comparison. Gas pressure tester - Designed for use in multiple industries including chemical, chemical fiber, electric power, and nuclear power. Offers versatile application for monitoring and validating gas pressures across various processes and systems. Gas gauge reader - Features an over-range prompt and calibration function, and is presented as a handheld digital manometer. Enables immediate alerts when pressures exceed limits and supports on-site calibration to maintain accuracy. Use scenarios - Monitor differential pressure across air filters or ductwork to determine when maintenance is needed and to optimize HVAC performance. - Verify gas supply pressures in chemical processing or power plants to ensure safe operation and compliance with standards. - Perform routine calibration and verification in field or lab settings to maintain sensor accuracy and process control.
