2in1 Test Pen 200mm

Test pens, also known as voltage testers or electrical testers, are handy tools used to check the presence of electrical voltage in circuits or outlets. They work by detecting the electrical field around a live conductor and typically have a long, pointed probe that is inserted into an electrical outlet or touched against a wire. When the probe comes into contact with live voltage, it completes a circuit, and the test pen indicates the presence of voltage through a visual or audible signal. Featuring a chrome-vanadium steel body, Ronix RH-2727 is a 200mm test pen that has dual functionality using its double-ended Phillips and slotted screw head.
