Is the resolution of your current mulitmeter inadequate to read the smallest signal? Need an easy to use multimeter with data-logging? Take a look at the GoodWill GDM-8255A series 5 1/2 digit dual-display digital multimeter. It features a DC voltage accuracy of 0.012% with an industry-leading response time. With robust hardware and software the GDM-825xA series will save time on debugging and analysis whilst saving you money. 

The GDM-8255A carries an extensive list of standard measurement items with a dual-display allowing two measurement items to be displayed simultaneously. Advanced measurement functions, such as Max/Min, Hold, Relative value and Compare, are suitable for a multiplicity of applications such as production testing, research and field verification. The USB, RS-232C and 9-pin digital I/O interface are included as standard features for romte control and data capturing for ATE.

For convenient PC-based remote control and extensive data capture, the GDM-8255A includes DMM-Viewer software at no additional cost. DMM-Viewer mimics the operation of the multimeters on the PC, allowing you to quickly use the software with little effort.

The optional scanner card (GDM-SC1A), creates a self-contained multipoint measurement solution with plug-in design.
