UEi Test Instruments EM152 Dual Differential Digital Manometer

Key features

• PROFESSIONAL 0.3% FULL-SCALE ACCURACY: A differential manometer rated to 0.3% FS accuracy across a 60 in. water column range. Measures positive, negative, and differential (delta-P) pressure from two inputs for reliable readings when setting gas pressure on furnaces, boilers, and appliances.
• 11 SELECTABLE UNITS WITH AUTO-RANGING: Switch between inH2O, PSI, Bar, mBar, kPa, inHg, mmHg, oz/in2, FtH2O, cmH2O, and kg/cm2 using the SCALE button. The auto-ranging design selects the right resolution automatically, with no manual range setting needed.
• DUAL-PORT DIFFERENTIAL TESTING: Use both ports for live differential measurement, or vent one port to read a single source. Built for HVAC static pressure, draft, gas supply, manifold, and burner pressure on natural gas and LP systems.
• RECORD, HOLD, ZERO: Capture Max, Min, and Average pressure with REC, freeze any reading with HOLD, and zero the sensors to cancel ambient drift. A large, high-contrast backlit LCD keeps digits readable in dark mechanical rooms and crawl spaces.
• HANDS-FREE AND FIELD-READY, BACKED BY UEI: A built-in magnet on the protective rubber boot frees both hands at the equipment, and it runs on a single standard 9V battery with auto power-off. Includes two 18 in. silicone hoses, a 1-year limited warranty, and ISO 17025-compliant, NIST-traceable calibration.
