2.8-inch backlit LCD for clear readings, a rugged IP54-rated enclosure, and USB data export for easy analysis in lab or fieldwork. High-precision handheld manometer with ±0.3% accuracy for differential, gauge, and absolute pressure measurements. Ideal for HVAC systems and industrial applications. Compact ergonomic design stores up to 100 datasets and runs on a 9V power supply, enabling easy pressure testing in demanding environments. Measures liquid pressure with 0.01 resolution for applications in ventilation systems, hydraulic machinery, Medicinal molding, and natural pipelines. Use scenarios - HVAC installation and service: verify duct static pressure, monitor filter resistance, and assess system pressure balance. - Industrial plant maintenance: track hydraulic circuit pressures and pipeline pressure drops to optimize processes and prevent equipment stress. - Field data collection: take readings in remote locations, store up to 100 measurements, and export via USB for analysis and reporting.
