Extech TKG100 is designed for making non-destructive measurements of wall thickness on primarily steel structures. TKG-100 provides a monochrome thickness readout. The TKG100 kit includes 2oz bottle of couplant, 2 AA batteries, transducer with potted cable, and hard case.
The hold mode retains the last thickness reading with reverse video display. The freeze mode freezes the display which is ideal for high temperature readings. The TKG100 beeps and flashes the display as well as keypad illumination.
