Quadtech 1880 Milliohmmeter
The Quadtech 1880 Milliohmmeter provides ease of use,
digital display and excellent accuracy for performing
low resistance measurements on switches, relays, connectors and a variety of other devices. The instrument
offers a wide measurement range, from 1 µohm to 2 Mohms, with constant current ranging from 1 A to 1 µA. A built-in
comparator makes the unit
ideal for go/nogo testing in a production
environment and is also adaptable for use in automated system applications
with its optional IEEE-488 interface.
