- Abstract : a portable digital instrument for multi - using ( multi - parameter ) is introduced . it includes the function of vacuometer , atmospheric pressure altimeter , thermometer ( environment ) and pressuremeter ( for example the standard pressuremeter of sphygmomanometer calibration )
- 4 . the thrust measurement device was calibrated , and the accuracy was 2 % fs . at the same time the signal of thrust measurement was input to the computer . e - type chromel - constantan thermocouple was used to measure the temperature of mpt , and the accuracy was 5 % fs . the vacuum measurement was realized by using zdf - 5427m vacuometer , and the accuracy was 3 % fs
- It's difficult to find vacuometer in a sentence.
