The BIOTEST from Metrix is a portable testing device for measuring low-frequency electric fields in the frequency range of 10 Hz to 3 kHz. It is used for detecting electrosmog generated by electrical distribution networks and is particularly suitable for testing electrical installations during new installations, renovations, or in technical training. The device features an internal antenna and displays the current field strength via two light bars, each with seven LEDs, enabling quick and intuitive assessment of exposure levels. The display is in the form of a level indicator, visually representing the strength of the measured electric field.

Applications
This device is designed for mobile use and is especially suitable for checking electrical systems in the field of residential installations, renovation work, or vocational training. It is used to monitor electric fields generated by power distribution systems and enables a simple, cost-effective, and compact inspection without external power supply. The application is primarily indoors, where electric fields are generated by wiring, sockets, or electrical appliances.

Functions and Equipment in Detail
The BIOTEST supports two measurement methods: measuring the electric field with consideration of a person's presence and measuring relative to ground. These two operating modes allow for a differentiated analysis of field conditions. Additionally, a socket tester is included in the delivery scope, which can check the position of the live conductor and the connection between the protective conductor and earth. This tester serves for safety inspection of sockets and allows verification of correct polarity and grounding.

Technology Explained Simply
The device operates on batteries and is therefore independent of mains power. The battery life is long, allowing extended use without recharging or battery replacement. The internal antenna detects electric fields in the frequency range of 10 Hz to 3 kHz, covering the range of low-frequency fields typically emitted by household power networks. The display is via LED light bars, visually representing field strength, enabling quick assessment of exposure levels.

Compatibility and Accessories
The device includes a socket tester for checking the live conductor position and protective conductor connection. This is directly included in the delivery scope. As suitable accessories, a transport bag with belt attachment is offered, allowing safe transportation and convenient carrying during mobile operations.

Mounting and Installation
The device requires no mounting or installation. It is operated directly by hand and can be used at any location in the room to measure electric fields. Operation is via simple controls described in the user manual. The manual is part of the delivery scope and contains instructions for correct use of the device and its integrated functions.

Advantages in Operation
The BIOTEST is characterised by its compactness, portability, and mains-independent operation. The long battery life and intuitive LED display facilitate daily use. The combination of field measurement and socket testing in a single device reduces effort when inspecting electrical systems. The application is simple and does not require special training, making the device suitable for use in training as well.
