Milli Ohm Meter/ Short Tracer

Unit can measure milliohms and give an audible indication when a short circuit location is traced to an individual component. <a href=""; target="_blank"></a>

ESR Meter

Instrument measures ESR (equivalent series resistance) of capacitors in circuit as displayed on a 10 LED bar graph meter. <a href=""; target="_blank"></a>

LC Meter

Measure Inductance and capacitance on a 8 x 2 LCD display. <a href=""; target="_blank"></a>

50 Ohm Bridge / Frequency Counter

Tune the bridge to the desired frequency & see a visual indication when the best 50 ohm match to an antenna is achieved. Has digital frequency LCD display. Unit also doubles as a 30 plus MHz frequency counter. <a href=""; target="_blank"></a>
