Forced Balanced Piston Gauge

The solution to very low pressure traceability FPG8601 addresses the need for a means of maintaining long term traceability with very low uncertainty in the pressure range under that covered by conventional piston gauges. The measurement range covered is from zero (0.5 Pa in absolute) to 15 kPa (112 Torr, 2.2 psi) in both gauge and absolute modes. Measurement uncertainty is the combination of ± 30 ppm of reading and a low end threshold component low enough to support the calibration of typical transfer standards with ranges as low as 130 Pa (1 Torr, 0.5 in. H2O), and even 13 Pa (100 mTorr, 0.05 in. H2O).
