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.

Features:

  • 10% of reading, 0.1 micron resolution
  • Can display in 12 different measurement units (microns, millitorr, torr, mm of Hg, mbar, bar, kPa, Pa, psia, inches of Hg, mm and inches of water)
  • Factory calibrated to NIST traceable standard
  • Auto Off
  • Battery level indication
  • Good/bad sensor (tube) indication
  • Self-test mode
  • Field replaceable sensor
  • 3 different graphical displays of vacuum pressure (pump-down, line, or bar graph)

Applications

  • Test vacuum pumps
  • Monitor evacuation
  • Leak test systems and components"
