DT-8897 Differential pressure Manometer and Flow Meter
The device measures Gauge/Differential Pressure, Air Velocity,Air Flow and temperature. Additional features include Data Hold. Auto Power Off disabled and an USB for capturing reading to a PC using optional software . Careful use of this meter will provide years of reliable service.
Features:
- Larger Dual LCD display with backlight.
- Relative time clock on MAX /MIN/ AVG provides a time reference for measurement.
- Pressure measurement provides Zero Adjust and DIF function.
- Display Pressure, Air Velocity or Air Flow plus Temperature simultaneously.
- Easy to set Area dimension (up to 8 point).
- USB interface, USB to UART Bridge Controller.
- Low battery indication, and Auto Power Off mode (Sleep mode) increases battery life.
- Data Hold
