The HT106D socket tester is a small yet very handy device that allows you to ensure safety in your home. It features an LED display that provides you with essential information. It alerts you to missing grounding and also enables you to test the residual current device (RCD). With the HT106D, you can prevent damage to your equipment and avert other hazards. Stay quickly informed about potential disturbances. The LED display on the top of the device indicates whether there are any issues. If the tester detects an anomaly, the LEDs light up in a specific combination. This way, you can quickly identify issues such as the disadvantages of live/neutral wires, missing grounding, or absent neutral conductors. The HT106D also allows you to perform a simple RCD test. Additionally, the device has a voltage measurement function, with results displayed on a clear LCD screen. The HT106D is characterized by high precision. With this practical device, you have easy access to the most important information.
