|
| 絕對壓力 |
± 2% of reading ± 0.1 in Hg from 14 to 40 in Hg referenced to vacuum.
60 psia maximum safe pressure. |
| 空氣密度校正 |
The air density correction range is 14-40 in Hg and 32°F to 158°F for
air flow measurement.
The readings represent local density air flow (cfm or L/s) corrected for barometric pressure. |
