1. SAFE AND CONVENIENT - The Voltage Pen Tester detects voltage in a non-Contact way, so do not worry about there could be any possibility of being shocked by the electricity.2.DIRECT & INDUCTANCE TEST - The Direct & Inductance test are the two main features in this tester. Direct test will provide the details on current and voltage flow. The Inductance test will find the ground line (earth wire) or break point of the phase line.3. INTERNAL AND EXTERNAL - The dust-proof and splashing water protection allows the device to be used both indoors and outdoors and come with integrated flashlight.4. LCD DISPLAY - This digital tester has an LCD display. The symbol represents the electric current flow. The tester can read voltage up to 220V and highlight 12, 36, 55, 110 and 220 volts. This helps you to determine which type of device to be used based on the device's operating range voltage.5. GEEPAS DIGITAL TESTER - Are you still using the Analog tester to check the issues in switch board, waiting for the light to blink? It is not only a primitive technology but also doesn't give you information on the voltage in the circuit. Geepas tools brings you a tester which not only gives you the current flow but also the voltage flow in the circuit.
