GW Instek launch a new series of D.C. milliohm meter ─ GOM-804/805, which abundantly feature 3.5-inch TFT display, maximum 50,000 counts measurement display, the rapid sampling rate of 60 readings per second, optimum 0.05% measurement precision, four wire measurement method as well as the temperature measurement and temperature compensation measurement function to meet the requirement of low resistance measurement application. The GOM-805 also includes various drive modes and Dry circuit for contact resistance measurement applications. More features, including 20 sets of panel setting memory and many external control interface such as RS-232C, USB, Handler/Scan/EXT IO or GPIB (option), greatly elevate GOM-804/805 milliohm meter’s convenience on practical applications.
- Totally replacing the existing models
- Faster measurement without sacrificing resolution
- Dry circuit test for GOM-805 only
- Various drive modes for GOM-805 only
- Standard interface for control and communications
- Command compatibility
