ZIBOO ET1015 Digital Dual Port Differential Pressure Gauge, 100 PSI Air and Gas Pressure Tester, Large LCD Display with Backlight, HVAC Gas Pressure Tester

This device measures differential, positive, and negative pressure in 11 units: inH2O, psi, bar, mbar, kPa, inHg, mmHg, ozin², ftH2O, cmH2O, and kgcm², making it a versatile tool for HVAC technicians and engineers. The ET1015 model, designed for high-pressure applications, offers a range of ±100.0 PSI (±6895 mbar / ±2772 inH2O) with high resolution and professional accuracy of ±0.3% FSO (25°C) and repeatability of ±0.2% (Max +/-0.5% FSO). It withstands up to 150 PSI, ensuring durability. With a user-friendly interface, it provides essential diagnostic functions like 'REC' mode for tracking fluctuations, 'HOLD' button for freezing readings, and 'DIF' button for calculating differential pressure. Its large, dual LCD display with backlight ensures clear visibility in dim environments. The zero-adjust function allows easy calibration, and it includes an Auto Power-Off feature and low battery indicator. The package includes a manometer, soft connection tubing, 9V battery, and a carry pouch, making it ideal for spot checks, clean rooms, gas furnace calibration, and pneumatic control systems.
