POROMETISTO DMT01 Digital Manometer – 12-Unit Dual Port Air Pressure Gauge
The POROMETISTO DMT01 Digital Manometer is a professional-grade differential pressure measuring instrument designed for HVAC technicians, engineers, and industrial professionals. With one-click switching across 12 pressure units and a fast 0.5-second response time, this dual-port gauge delivers accurate, reliable readings for natural gas pipelines, ventilation ducts, airtightness inspections, and laboratory environments. Made in China.
Key Features
- 12 Pressure Unit Switching: Instantly toggle between inH₂O, PSI, mbar, kPa, inHg, mmHg, oz/in², ftH₂O, mmH₂O, cmH₂O, kg/cm², and bar — all at the press of a button.
- Triple Measurement Modes: Measures positive pressure, negative pressure, and differential pressure; one-touch differential mode captures pressure changes instantly.
- High Accuracy: ±0.3% FS accuracy with a ±5 PSI measuring range and maximum overpressure rating of 10 PSI.
- Max / Min / Avg Recording: Real-time logging of maximum, minimum, and average values for comprehensive data analysis.
- Data Hold Function: Lock the current reading on-screen with a single press.
- Manual Zero Reset: One-click zero calibration ensures precise differential pressure readings every time.
- Adjustable Auto Power-Off: User-configurable shutdown (set ON/OFF for under or over 5 minutes) to preserve battery life.
- Backlit LCD Display: One-touch backlight activation for clear readings in low-light or nighttime working conditions.
- Relative Time Display: Tracks measurement duration in real-time.
- Under-Voltage Indicator: Alerts you when battery replacement is needed.
- CE & RoHS Certified: Meets international safety and environmental compliance standards.
