Multimeters & Test Devices - Test Technology for Experts

Multimeter: The heart of measurement technology

Multimeters, also known as multi-function meters, are versatile instruments used in many areas of electrical engineering. They offer a wide range of functions and features, from measuring basic electrical quantities to specific tests for electronic components. 

The main types of multimeters include: 

• Handheld multimeters: These compact and lightweight devices are ideal for technicians who perform measurements on site. They offer mobility and flexibility for quick diagnostics and repairs. 
• Bench multimeters: These devices are characterized by high precision and stability and are particularly suitable for demanding laboratory environments. They enable simultaneous monitoring of multiple parameters and are designed for long-term installations. 
• Built-in multimeters: These devices are designed for rack mounting in industrial plants and are ideal for continuous monitoring tasks. They offer advanced data acquisition and analysis capabilities and can be easily integrated into larger measurement systems. 

Modern multimeters feature advanced functions such as high-resolution displays, automatic range selection, and protection mechanisms against overload and voltage spikes. These features improve usability and safety, making them valuable tools in any technical equipment.

Battery measurement technology

Battery measurement technology encompasses a wide range of devices used to test and analyze individual cells, battery modules, and high-performance energy storage systems. This technology is essential for applications in research, development, and production, particularly in the manufacture of energy storage systems for photovoltaic systems and electric vehicles.

The main applications of battery measurement technology are:

• Characterization: Determining the performance and efficiency of batteries. 
• State of charge (SOC) determination: Monitoring the current state of charge. 
• Aging tests: Evaluating service life and aging processes. 
• Suitability analyses: Testing suitability for specific areas of application.

Battery testers enable precise measurements and provide important data for improving battery quality and performance. These devices are indispensable for rapid diagnosis and analysis and help users make informed decisions about the condition and performance of batteries. 

High-voltage battery measuring devices are specially designed for precise voltage and internal resistance measurement of high-voltage batteries. These devices are particularly useful for demanding applications in development and maintenance. They ensure that batteries operate safely and efficiently and help to identify potential problems at an early stage.

Safety testers

Safety testers are crucial for checking and ensuring the electrical safety of devices and systems. These testers check whether products comply with applicable safety standards and norms in order to minimize risks such as electric shocks, short circuits, and other hazards.

The main functions of safety testers include: 

• Continuity test: Checking the electrical connection. 
• Insulation test: Measuring the resistance between electrical conductors. 
• Voltage test: Testing the dielectric strength of insulation. 
• Leakage current test: Determining unwanted currents flowing through the insulation. 

These devices are used in various industries, including electronics manufacturing, medical technology, and the household appliance industry. They are indispensable for quality assurance and ensure that products meet the highest safety requirements. 

Different types of safety testers offer specific functions for different applications. These include portable devices for on-site use and stationary systems for comprehensive and reliable testing in laboratory environments. Modern safety testers have advanced features such as automatic test sequences, data recording, and interfaces for integration into larger test systems.
