Differential Pressure Gauge Digital Manometer Dual Port Air Pressure Tester HVAC

Key Features

🔵 Dual-Port Differential & Single Pressure Measurement
Measure pressure from a single pipe or the difference between two pipes. Perfect for HVAC systems, ventilation balancing, gas appliance testing, and filter pressure drop checks.

📊 ±2.999 psi (±20.68 kPa) Range with High Resolution
0.001 psi resolution gives you precise, lab‑grade readings for sensitive low‑pressure systems – from cleanroom environments to gas burner pressures.

🔄 13 Selectable Pressure Units
No manual conversion needed. Switch instantly between:
psi, kPa, bar, mbar, Pa, kg/cm², oz/in², inH₂O, ftH₂O, cmH₂O, inHg, mmHg, and °C/°F temperature display.

🧮 Data Hold, Zero & Max/Min Recording

• HOLD button freezes the reading.

• Press HOLD >2 seconds to zero the meter – essential for differential offset.

• MAX button tracks peak and lowest pressures during your test.

📲 Data Storage (100 points) & Recall
Store up to 100 readings on site, then review them later using the DIF and MAX buttons. No need for pen and paper.

🔦 Backlit LCD & Auto Power Off
Clear display works in dark boiler rooms or outdoor cabinets. Auto‑off after 15 minutes saves battery – and a low battery icon warns you in time.
