Product advantages

1. Triple measurement

Measures the radiation strength of cordless telephones, WiFi, Wi-Fi, mobile phone stations, high-voltage lines, electrical installations, baby monitors, microwave herds, mobile phones, etc.

2. Easy handling

Quick and easy location of electromagnetic sources (electrosmog) to be able to switch them off in a targeted manner.

3. No expertise necessary

The device shows the strength of the radiation through green (low), orange (medium) and red (high) LEDs.

Cemprotec 33: Multiple detector for electromagnetic fields

The Cemprotec 33 developed in France is a state -of -the -art detector with which the entire electromagnetic spectrum (electrical, magnetic and high -frequency radiation) can be measured.


The level of electromagnetic radiation is constantly increasing. With the detector Cemprotec 33 you can control your exposure level and identify the sources to avoid overexposition to electromagnetic waves. It is a very practical tool for every day!

High frequency mode for 3G, 4G and 5G

With highly sensitive antennas with a sampling frequency of 20 kHz, the harps of the harp measures the 3G, 4G or 5G high frequencies with ease; This is a real advantage for electrical -sensitive people.

Easy handling

The operation of the device was designed as simple and intuitive as possible. The first button is used to switch off the device on and off. With the second button, the two main functions can be accessed.

Electrical sockets

The harpsichord 33 enables electrical fields to be recognized with great ease! For example, it is very easy to check the alignment of the plug with a bedside lamp. When the plug is inserted in the right direction, it generates significantly less radiation in the head area when the lamp is switched off. Try it out yourself!


The harpsichord 33 is extremely practical and the only detector that enables a three -dimensional recording of magnetic fields (in 3D from 10 Hz to 10 GHz). This ensures high accuracy regardless of the alignment of the device or the source of the field.

Electrical fields

Electrical fields are created by power lines, both low voltage and high voltage, as well as from all electrical devices connected to the power grid. The harpsichord 33 enables easy and effective recording of electrical radiation from 10 Hz to 5 kHz.

HF wave

Recording of high frequency radiation: This includes all wireless systems such as B. networked devices, WLAN, mobile phone masts, mobile phones, cordless landfill phones, alarm systems, bluetooth devices, baby fones, 5G etc. The harpsichord antenna is equipped with a broadband antenna that captures a very wide range of radiation in the range from 1 MHz to 8 GHz .
