Although at first glance the screwdriver looks like a normal screwdriver, if observed closely reveals many differences. It has a transparent and isolated handle, in which there is a small neon bulb connected to the blade of the screwdriver: if the tip touches a part where there is tension, the light bulb turns on.

The screwdrivers are manual tools for very important electricians, because they allow to detect any malfunctions in a circuit and allow you to verify that all the parts of a circuit, new or old that it is, work properly. However, it is a very delicate tool, which must be handled with extreme care: in fact, if it falls or suffers a strong blow, the resistance is damaged and the connection with the light bulb stops working.

In the catalog of Mister Worker™ there are numerous professional screwdrivers of the best brands on the market, such as Facom, Expert and Stanley, each ideal for measuring a certain type of voltage.
