DM5 Dual Digital Manometer Specifications
| Feature | Specifications |
| Sensors: | 2 independent differential pressure transducers with auto zeroing |
| Pressure Resolution: |
Display resolution is 1 Pa from -7.5 kPa to +7.5 kPa or 0.01 "wc from -30.00 "wc to +30.00 "wc. Internal resolution is 1/4 Pa or 0.001 "wc and this is the resolution of the serial output. |
| Pressure Range: |
Bi-directional: ±30.00 "wc and ±7.500 kPa. For lower pressures, see the Infiltec DM4 |
| Keys: | 7 mode selection keys. |
| - Device Key: | Select: Manometer or Pitot tube modes. |
| - Units Key: |
Dual Manometer: Metric (Pa, Pa), U.S. ("wc, "wc), Mixed ("wc, Pa) Pitot flow: Metric (Pa, m/s), U.S. ("wc, fpm), Mixed (Pa, fpm) |
| - Time Avg Key: | Select block average of 1 (default), 2, 4, 8, 16, 32 or 64 seconds. |
| - Low Flow Key: |
Dual Manometer: no function Pitot flow: no function |
| - Baseline Key: | Resets zero pressure. |
| - Hold Key: | Holds reading on display until pressed again. |
| - On/Off Key: | Turn power on and off. |
| Accuracy: |
Dual Pressure: ±1% of display measurement or ±1 digit, whichever is greater. Pitot Flow: ±1.5% of measurement or better from 2540-21000 fpm (12.9-110 m/s) |
| Display Type: | 2x16 high contrast LCD with numbers and characters. |

| Maximum Pressure: | ±250 "wc, ±60 kPa or ±9 PSI |
| Low Battery Display: |
Current battery voltage is displayed at startup, "lowbat" displayed when voltage is under 7 volts. |
| Over Range Indicator: | !!MAX!! displayed when pressure is beyond ±30 "wc or ±7.5 kPa. |
| Auto Zero: | Pneumatic switches update zero pressure estimates every 8 seconds. |
| Weight With Battery: | ~16 oz. (~455 grams) |
| Dimensions: | 4.0"x7.5"x1.79" (101.6x190.5x45.4 mm). |
