Digital Multimeter

This tool accurately measures DC/AC voltage, DC current, resistance, diode test and audible continuity. The dual-slope A-D converter uses C-MOS technology for auto-zeroing, polarity selection, and over-range indication. ST-5505 is an ideal instrument for use in the field, in the laboratory, in the workshop, in the hobby and at home.
