Since
pressure gauges subjected to agitation frequently go out of adjustment,
means for easily detecting and correcting such error is imperative, particularly
when the gauge reading is critical, as in use with the Series 1000/2000
Zahm CO2 Gas Volume Meters and the various Zahm Piercing Devices. The Zahm
Gauge Tester (Series 8000) provides a highly accurate means of re-calibrating
pressure gauges in the laboratory. |
