With 11 selectable units and a wide ±30 psi range, it is an\nessential tool for HVAC system calibration, natural gas pipeline pressure\ntesting, ventilation troubleshooting, air quality monitoring, and appliance\ninstallation. Key Features High Precision Measurement: ±0.3%FSO accuracy at\n25°C, ±0.25% repeatability, and ±0.1%FSO linearity\/hysteresis ensure reliable\nresults on every job.11 Selectable Units: Instantly switch between psi, kPa,\nkgf\/cm², oz\/in², bar, mbar, inHg, mmHg, inH₂O, ftH₂O, and cmH₂O — no manual\nconversion needed.Dual-Port Design: Measure pressure difference between two\npoints simultaneously, perfect for filter monitoring, duct airflow balancing,\nand valve testing.Data Recording \u0026amp; Hold: Built-in recording mode captures MAX,\nMIN, and AVG values. Data Hold function freezes the display for easy\ndocumentation.One-Touch Zero Setting: Quickly calibrate the baseline before\neach measurement to ensure accurate readings.Clear Backlit Display: Large LCD\nwith backlight ensures easy reading in dim environments such as basements,\nutility rooms, and crawl spaces.Smart Power Management: Auto power-off after\n25 minutes of inactivity preserves battery life. Low battery indicator alerts\nyou before power runs out.
