Welch Digital Vacuum Gauge
Besides the traditional vacuum gauges with mechanical sensors e g bourdon capsule gauge diaphragm manometers with electronical diaphragm sensors are well established piezo and capacitance gauges.
Welch digital vacuum gauge. The pressure to be measured is separated by a diaphragm from a reference vacuum and compared to the latter. It is a highly accurate full range digital millitorr gauge using field proven thermocouple vacuum sensor technology. Particular sensors and gauges must be used for parts of the whole range rough high and ultra high vacuum. The diagnostic vacuum gauge 1515 is a portable vacuum measurement instrument designed specifically for the demands of field use.
It is a highly accurate full range digital millitorr gauge using field proven thermocouple vacuum sensor technology. Printed from sargent welch website user. The total range of scientifically useful vacuums extends from approx. A physical measurement of the whole vacuum pressure range is not necessary.
1526 model diagnostic vacuum gauge welch model 1526 diagnostic vacuum gauge is a rugged portable vacuum measurement instrument designed specifically for the demands of field use. 1000 mbar atmospheric pressure down to 10 12 mbar the ultra high vacuum range.
