Professional Voltage Testers from HDT

The voltage tester is the most important tool for the electrician; he uses it to determine the absence of voltage on operationally live parts and trusts its safe function for the rest of his life. Voltage testers are divided into single-pole (also called phase testers) and double-pole voltage testers, which provide a safe test result.

The highest safety requirements are shown in a special standard for two-pole voltage testers, the EN 61243-3 in its current version 2014.

Furthermore, there are non-contact voltage testers, which are mainly used in the American market and to search for cable breaks. They are not suitable for reliably detecting the absence of voltage.

The product range of simple voltage testers consists of low-priced models that have basic functions and comply with current safety standards.

HDT is the world's leading OEM/ODM manufacturer of voltage testers and offers suitable products for every application, which are described below.

As the market leader in 2-pole voltage testers, we cover the requirements for highest safety and most comprehensive functions - from the beginner to the professional. Also available with your housing!

Voltage testers with IP2X tip protection

A further feature of 2-pole voltage testers are models with protected test probes. Originally required by the EDF in France, the metal tips have an insulating protective sheath which must first be removed for measurement by spring force or 2-hand release. This is to prevent possible short circuits. And according to the latest standard EN 61243-3, higher loads than the 3.5 mA at 230 V are also permissible, for example to trigger a residual current circuit breaker.

Non-contact voltage testers

Non-contact voltage testers detect the electric field strength emitted by a conductor or other live parts such as sockets. This is then indicated to the user by means of an LED, a sound generator and/or a vibration motor. However, this only works with AC voltage and not with DC voltage.

HDT offers a wide range of products here, from simple analogue voltage detection to rotary field detection in the 3-phase network and digital interference filter.

Cookies

Some of our web pages use cookies. Cookies do not harm your computer and do not contain any viruses. Cookies help make our website more user-friendly, efficient, and secure. Cookies are small text files that are stored on your computer and saved by your browser.

You can configure your browser to inform you about the use of cookies so that you can decide on a case-by-case basis whether to accept or reject a cookie. Alternatively, your browser can be configured to automatically accept cookies under certain conditions or to always reject them, or to automatically delete cookies when closing your browser. Disabling cookies may limit the functionality of this website.

Cookies which are necessary to allow electronic communications or to provide certain functions you wish to use (such as the shopping cart) are stored pursuant to Art. 6 paragraph 1, letter f of DSGVO. The website operator has a legitimate interest in the storage of cookies to ensure an optimized service provided free of technical errors. If other cookies (such as those used to analyze your surfing behavior) are also stored, they will be treated separately in this privacy policy.

  • Browser type and browser version
  • Operating system used
  • Referrer URL
  • Host name of the accessing computer
  • Time of the server request
  • IP address

These data will not be combined with data from other sources.

The basis for data processing is Art. 6 (1) (f) DSGVO, which allows the processing of data to fulfill a contract or for measures preliminary to a contract.

Contact form

Should you send us questions via the contact form, we will collect the data entered on the form, including the contact details you provide, to answer your question and any follow-up questions. We do not share this information without your permission.

We will, therefore, process any data you enter onto the contact form only with your consent per Art. 6 (1)(a) DSGVO. You may revoke your consent at any time. An informal email making this request is sufficient. The data processed before we receive your request may still be legally processed.

We will retain the data you provide on the contact form until you request its deletion, revoke your consent for its storage, or the purpose for its storage no longer pertains (e.g. after fulfilling your request). Any mandatory statutory provisions, especially those regarding mandatory data retention periods, remain unaffected by this provision.

Google reCAPTCHA

We use "Google reCAPTCHA" (hereinafter "reCAPTCHA") on our websites. This service is provided by Google Inc., 1600 Amphitheater Parkway, Mountain View, CA 94043, USA ("Google").

reCAPTCHA is used to check whether the data entered on our website (such as on a contact form) has been entered by a human or by an automated program. To do this, reCAPTCHA analyzes the behavior of the website visitor based on various characteristics. This analysis starts automatically as soon as the website visitor enters the website. For the analysis, reCAPTCHA evaluates various information (e.g. IP address, how long the visitor has been on the website, or mouse movements made by the user). The data collected during the analysis will be forwarded to Google.

The reCAPTCHA analyses take place completely in the background. Website visitors are not advised that such an analysis is taking place.

Data processing is based on Art. 6 (1) (f) DSGVO. The website operator has a legitimate interest in protecting its site from abusive automated crawling and spam.

For more information about Google reCAPTCHA and Google's privacy policy, please visit the following links: https://www.google.com/intl/de/policies/privacy/ and https://www.google.com/recaptcha/intro/android.html.

5. Newsletter

Newsletter data

If you would like to receive our newsletter, we require a valid email address as well as information that allows us to verify that you are the owner of the specified email address and that you agree to receive this newsletter. No additional data is collected or is only collected on a voluntary basis. We only use this data to send the requested information and do not pass it on to third parties.

This website uses CleverReach to send newsletters. The supplier is CleverReach GmbH & Co. KG, Mühlenstr. 43, 26180 Rastede. CleverReach is a service which organizes and analyzes the distribution of newsletters. The data you provide (e.g. your email address) to subscribe to our newsletter will be stored on CleverReach servers in Germany.

Sending our newsletters with CleverReach enables us to analyze the behavior of newsletter recipients. Among other things, we can find out how many recipients have opened the email containing the newsletter and how often various links contained therein are clicked. With the help of conversion tracking, we can also analyze whether a predefined action (such as the purchase of a product on our website) takes place after clicking on the link in the newsletter. For more information on how data is analyzed by CleverReach, please visit https://www.cleverreach.com/de/funktionen/reporting-und-tracking/.

Data processing is based on Art. 6 (1) (a) DSGVO. You may revoke your consent at any time by unsubscribing to the newsletter. The data processed before we receive your request may still be legally processed.

If you do not want your usage of the newsletter to be analyzed by CleverReach, you will have to unsubscribe from the newsletter. For this purpose, we provide a link in every newsletter we send. You can also unsubscribe from the newsletter directly on the website.

The data provided when registering for the newsletter will be used to distribute the newsletter until you cancel your subscription when said data will be deleted from our servers and those of CleverReach. Data we have stored for other purposes (e.g. email addresses for the members area) remains unaffected.
