Wall thickness gauge TT700

High performance in a light and handy size

The operator keypad interface is user-friendly and has a central mode key, a calibration key, three function arrow keys to activate and set functional control and navigate through the menu plus a key to store/transfer data. It has an integrated steel calibration plate and the display resolution can be switched from 0.001 to 0.01mm. If you need to document your measuring results, they can be printed or transferred to a PC. 

Features

  • Super-easy keypad handling
  • Integrated calibration plate
  • Selectable between…
        …Measurement value in mm or inch
        …Display solution in 0,001 or 0,01 mm
        …Sound velocity testing or single point calibration
        …I-E, E-E or AUTO testing mode
  • I-E: For measuring thick test pieces, but the results are easily influenced by the coupling status
  • E-E: For measuring test pieces up to a certain thickness limit, but the measuring result will be accuracy and stable
  • AUTO: the instrument will select I-E or E-E automatically
  • PC transfer and printing
  • Sound alarm, backlight, shutdown after 2 minutes and differential mode are available
  • Data store, view and delete
  • Only 220 g
