Multifunctional Meter: DROK multimeter panel is available to measure percentage and AH of remaining capacity, DC positive and negative bidirectional current, DC voltage, DC positive and negative power, DC positive and negative bidirectional accumulated electric energy. Voltage measurement range is DC 0-300V, current measurement range is 0-200A.

Hall Sensor & Easy Mount: the voltage amperage meter is coming with a Hall transformer to for isolated measurement, reliable and safe; accepting two-wire system connection and three-wire system connection, could be powered DC5~90V, easy and simple to wire this meter up.

Display: backlight can be controlled to be ON or OFF as user's need; Equipped with full angle of view LCD screen, users could see the display clearly whenever at night and day, indoor or outside, even under the sunshine.

Alarming Function: it will alarm and flash to draw your attention when the real voltage is higher or lower than preset alarming voltage and real current is higher than preset current; It will also alarm and flash to remind you to charge for your device when the remaining capacity of battery is low.

Wide Applications: Can be used as dc amp meter, digital volt meter, power meter, battery capacity monitor. Suitable for all kinds of batteries, such as Lead-acid batteries, Lithium Polymer batteries, lithium iron phosphate batteries and etc. With function of storing date when power down, using this meter, no need to worry that your electric data will be lost.
