The Texmate UM-35-DCA is a cost-effective DC current meter that measures DC signals as low as 20mV full scale. The UM-35-DCA is ideal for high DC current measurement using low voltage drop current shunts, or for other precision low DC mV measurements. This meter comes standard with a red 3 1/2 digit LED display or you can choose an optional green or super bright LED display.
