AEMC K110 [2111.73] 100A AC/DC Microprobe, 10mV/mA, 450mA Max. The DC/AC Microprobe Model K110 measures as low as 100A AC or DC. The unit has proportional mV output for direct readings on DMMs. The high accuracy K110 is ideal for calibration of current loop process instruments (e.g., 4 to 20mA or 0 to 20mA). It has an ultra-compact size and non-contact clamp-on convenience. No range or mode (AC/DC) switching required.
