Digital socket tester with LCD HT106D – Quick and safe checking of electrical wiring
Home and office safety starts with a flawless electrical installation. The Digital Socket Tester with LCD (SKU: HT106D) is an extremely accurate, reliable and indispensable instrument for quickly testing electrical sockets. This small but extremely powerful device allows you to identify possible wiring faults, check the operation of the residual current device (RCD) and measure the mains voltage in seconds.
Thanks to its intuitive design and clear LCD display, the tester is suitable for both professional electricians and DIYers who want to ensure the safety of their loved ones and protect valuable electrical devices from damage.

Why choose the HT106D digital socket tester?
Incorrectly connected sockets, missing earthing or swapped phase and neutral conductors can cause serious damage to electrical appliances, and in the worst case even fire or electric shock. Using the HT106D tester you can elegantly avoid these dangers.
Key benefits for your safety:

Immediate fault diagnosis: LED indicators on the top of the device with light combinations immediately reveal the socket status (e.g. lack of grounding, lack of neutral cable or reversely connected cables).
Accurate voltage measurement: Voltage and frequency measurement results are displayed on a clear, high-resolution LCD screen.
Built-in RCD test: Simple test of the operation of the residual current device (RCD) with a single push of a button.
Backlight: The screen is equipped with a bright backlight, which allows for uninterrupted work and easy reading of data even in dark corners or poorly lit rooms.
Compact and durable: It is made of high-quality materials that ensure a long service life, while weighing only 50 grams, which means you can always carry it with you in your pocket or tool bag.

How does the HT106D socket tester work?
Using the device is extremely simple and does not require any prior professional knowledge:

Connection: Simply insert the tester into the electrical outlet you want to test.
Voltage reading: On the illuminated LCD screen you will immediately see the current voltage (V) and frequency (Hz) of the electrical network.
Checking the wiring: The LED indicators on the top of the device will light up in a specific combination. There is a handy legend on the device housing that immediately tells you whether the wiring is correct or if there is a fault (e.g. missing ground, reversed phase/neutral, etc.).
RCD test: To test the residual current device, press the RCD test button. If the device is working properly, the current will be interrupted.


Frequently Asked Questions (FAQ)
What does the acronym RCD stand for and why is this test important?
RCD (Residual Current Device) is a residual current device (often called a residual current device). Its function is to turn off the electricity in milliseconds in the event of a current leak (e.g. when a person comes into contact with electrical voltage) and prevent fatal electric shock. The HT106D tester allows you to quickly check whether this switch in your home is working properly (triggered at a current >30mA).
Can the tester damage my electrical devices?
No. The tester is designed exclusively for measuring and diagnosing the condition of the socket and operates within a safe voltage range of AC 48-250V. It is manufactured in accordance with the strictest safety standards EN61010-1 and CAT II 300V, ensuring completely safe use.
Does the tester need batteries to operate?
No, the HT106D digital socket tester is powered directly from the electrical outlet you are testing. This means the device is always ready to use, without worrying about dead batteries.

Same summary

The digital socket tester with LCD is suitable for users who want to quickly and easily check electrical sockets and basic voltages at home or in the workshop. The digital version displays results clearly and accurately, which is especially useful for basic repairs and beginner electrical work. The device is handheld and portable, which allows for easy use in different locations, but the maximum measurement range of up to 300 V may limit its use for measurements above this threshold. For more advanced needs or specialized functions, it is worth considering models with a larger measurement range or additional features.
