Description
Welch Model 1526, Diagnostic Vacuum Gauge, is a rugged, 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. Model 1526 offers several viewing options including numeric, bar graph, line graph and pump down graph display as well as vacuum analytics for leak, outgassing and pump-down rates.
Model 1526 replaces gauge 1525B-01 and gauge kit 1525K-10.
