The Stanley digital detection screwdriver is useful for testing led display voltage and electrode testing for electric current lower than 12V. The product has the characteristics of direct detection 12V-220V AC/Dc live objects, dispensing with battery, economic benefits and rapid induction voltage testing and LED display. This item has passed CE certification by the EC. This product comes with one piece of direct detection probe and one piece of black plastic storage box. It is made up of one main body, one detection probe and two spare electrodes. The main body is composed of two parts, a white plastic body and a metal head. The advantage of the product is that it can directly detect AC voltage from 0 to 250V without using any battery or condenser. It also tests Dc current from 0 to 12A without using any battery or condenser easily. The Dc current value will be shown on the dial which has been calibrated in ohms for testing Dc current lower than 12A. This item also can test voltage from 0 to 250V directly without using any battery or condenser. Both Dc current and AC voltage can be displayed on the screen which shows in LED display when it is turned on. The Stanley digital detection scope is a device for testing led display voltage and electrode testing for electric current lower than 12V. The device has a digital display, which makes it much easier to read than other devices of the same kind. The fact that it uses electricity only when testing means that the battery will not consume any energy while stored in a drawer, which will save you more money in the long run.
