An ESD tester that is worth seeing The design

A masterpiece of engineering, manufactured in Germany, our ESD tester sets standards in terms of precision, reliability and durability.

The high-quality design of our ESD tester is not only aesthetically pleasing, but also functionally well thought out. Every detail has been carefully designed to not only make it easy to use, but also to ensure a robust structure. The EPA Gatekeeper is not just a tester, but a statement of quality and excellence.

The proximity sensor automatically wakes up the device when a user approaches. If no further measurements are taken, the device switches back to stand-by mode. The stand-by mode saves energy and at the same time ensures a long service life for the display. Due to the great influence of temperature and humidity on the
ESD measurement, these parameters are also monitored by the built-in sensors and archived in the measurement data for each measurement.

Plug and Play No additional server or client software

The EPA Gatekeeper has been designed to provide you with a comprehensive solution without the need for additional servers or client software, which means: no hidden costs, no complex installations. The freedom offered by our ESD personnel screening device lies not only in its technological superiority, but also in its ease of use.

Without the need for additional servers or client software, you experience effortless commissioning - simply plug in and start your ESD personal checks - just like plug and play - without tedious configurations. Say goodbye to hidden fees and license costs. With our ESD personnel tester, you have a transparent and future-proof investment.

Intelligent ESD personal testing equipment Network functionality

The EPA Gatekeeper enables network operation without additional server software. Up to 64 devices independently form a network and synchronize their data with each other. The self-networking capabilities of our ESD personal inspection devices enable them to connect seamlessly with each other and form an intelligent network. This smart network not only offers effortless integration into your existing infrastructure, but also increased flexibility when carrying out ESD personnel testing. Manage multiple test devices from a central point and maintain full control of your test environment.

IT updates at the customer's premises therefore have no effect on the functions and operation of EPA Gatekeeper.

Ergonomic operation Easy ESD verification of the wrist strap

The modern design of our ESD personal tester is characterized by clear lines, an elegant surface and well thought-out ergonomics. The front of the device is equipped with high-quality stainless steel touch surfaces on both sides. The arrangement of the touch surfaces enables ergonomic operation for left and right-handed users. The measurement is started by touching one of the two stainless steel touch surfaces. The solid stainless steel connections on the front of the device allow the wrist strap to be checked in accordance with current standards. All three connections are equally connected to each other. This also ensures a long service life, especially for ESD measuring and testing devices in daily use.

Go for quality, go for durability, go for style. With our ESD personal tester, you not only get a reliable tester in your home, but also an aesthetic statement that meets your professional requirements.

Chic, elegant and functional at the same time - EPA Gatekeeper.

ESD documentation made easy The card reader

Our integrated multifunction card reader reads all common methods with maximum precision and speed. This allows customers to use existing RFID chips/cards, which means that the identification of the people being checked is effortless and efficient, significantly speeding up the checking process.

The RFID reader always reads the UID as the primary ordinal number. Adaptations for reading other ordinal numbers are possible on request.

The special feature of the EPA Gatekeeper is the flexibility of the integrated card reader. Even on small models, this can be upgraded at any time to ensure that your device can keep pace with the growing needs of your business. This additional service gives you the freedom to expand the functionality of your device as required.

Successful ESD measurement Signalized by halo light effect

Experience the innovation of visual feedback in ESD personnel testing with the EPA Gatekeeper!

The device exclusively features the unique HALO light effect. This innovative light indicator sets new standards by providing a clear and intuitive signal for successful or poor measurements at a glance - a function that only our device has. When measurements are successful, the HALO lights up in a reassuring shade of green, while when measurements are poor, a striking red light indicates that access to the ESD protection zone is not possible.

The integration of the HALO light effect is not only a technological masterpiece, but also a visual statement of quality and innovation. This unique feature sets the EPA Gatekeeper apart from other testing devices and offers you an unparalleled level of control and safety.

AddOn Expand the scope of your device

What makes our ESD personal tester truly outstanding are our available add-ons, with which you caninvest not just in a product, but in a long-term solution for your ESD requirements.

Our add-ons are software components that extend the functionality of your EPA gatekeeper. Installing one of our add-ons allows you to customize or improve the basic functionality of the ESD tester according to your individual needs.

An add-on can be purchased directly with an EPA gatekeeper, but can also be purchased at any time afterwards. This allows you to improve the performance of your devices and adapt them to specific requirements.

Efficient work The web server

The web server of our ESD personal verification device opens the door to a world of administrative freedom. Administrative settings, such as uploading a user database or creating a network share for data storage, can be easily configured here to adapt the device's functions to your company's individual requirements. The web server offers you a central interface for comprehensive control.

A particular highlight is the function for viewing the measurement history. With the help of web access, you can easily and conveniently access a detailed overview of all ESD measurements performed.
