UNCERTAINTY EVALUATION OF LOW PRESSURE BY MEANS OF CROSS-FLOAT

• Abstract:

  KTL has forced piston gauge which generate very low pressure (1 Pa ~ 1400 Pa) stable. Prior to forced piston gauge, we calibrate with digital manometer or capacitance diaphragm gauge below 1400 Pa (uncertainty: 0.011 %). This paper will introduce uncertainty evaluation of new standard by means of cross-float.
