Drok Voltmeters
-
Product Highlights- Through-hole design: easy wiring; measure positive or negative current; no current direction limitation
- Compatible with large wire; diameter of the sensor hole is 3/4 inch(19 mm)
- Dual display: display voltage and (+ -)current at the same time; voltage range: 5v-100v; current range: 0-100a
- Electrically isolated from high voltage power source which eliminates risk to delicate monitoring equipment and also minimizes safety concerns
- Loop through sensor multiple times to strengthen signal. for example, if your current signal is only 0.2 amps, you could loop the wire through the sensor 10 times and the signal would by 10x stronger and would appear as 2.0 amps

Product Highlights
- The meter should be powered by an isolated and not common ground power supply, the power supply is dc 3.8-32v, with reversed connection protection.
- Current sampling uses an independent ad conversion chip, more accurate and stable; the meter should be connected to the negative to measure current.
- The dc 0-100v 100a multimeter can measure positive voltage and positive/negative, the decimal point will flash when measuring negative current.
- Four digits led display is clear and bright enough with red violet & blue amp, the decimal point will automatically move when less than 1a, unit is ma.
- Very suitable for monitoring the condition of the battery, or the places where need accurate measurement.
