Description
Description
The Testkey TK2518 scanning resistance meter measures from 1 µΩ–2 MΩ using four-terminal connections. Select the exact model by the installed channel count shown below. Standalone and scanning modes share the color display and temperature compensation functions.
TK2518, TK2518A, TK2518B and TK2518-30 include 20, 10, 4 and 30 channels respectively. The standard TK2518-30 supplies 30 channels. Optional expansion to 200 channels requires additional scanning hardware.
