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 µΩ to 2 MΩ, 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.
Uses:
- Production Testing for Contact Resistance of Switches, Relays, Connectors, Cables, Printed Circuit Boards and Other Low Resistance Devices
- Component Testing of Resistors, Motors, Fuses, Squibs and Heating Elements
- Incoming Inspection and Quality Assurance Testing
- Conductivity Evaluations in Product Design
Features:
- Measurement Range, 1 µΩ to 2 MΩ
- 1 µA to 1 A, Constant Current
- 0.05% Measurement Accuracy
- Measurement Speed of 5/second
- Easy to Read Digital Display
- Four-Terminal Kelvin Connections
- Automatic Zeroing
- Built-in Comparator for Go/NoGo Testing
- Display of % Deviation from Nominal
- Auto Ranging
- Remote Control Interface
- Optional IEEE-488 Interface
