Test Resistors
Our test resistors for use in laboratories, educational institutions, or development environments: Precise. Durable. Versatile.
What is a test resistor?
A test resistor is a key component in a wide range of testing and experimental applications – from development and quality assurance to education. Whether in industry, research, or teaching: wherever electrical or electronic components need to be tested using real ohmic loads, reliable and robust test resistors are essential.
The right test resistor for every setup
FRIZLEN offers a broad portfolio of resistors for experimenting and testing, tailored to a wide variety of requirements. Our devices support both simple functional tests and complex load or endurance tests. They are available with fine or stepped adjustment, for stationary or mobile use, and in various protection classes – from open-frame designs to encapsulated solutions for industrial environments.
Typical applications include testing of generators, power supplies, and batteries, as well as switchgear and power electronics. For use in laboratory environments – such as in schools, universities, or R&D departments – we offer specially designed devices with safe handling and practical features such as voltmeters, terminal sockets, or safety switches.
Thanks to our in-house development and high manufacturing depth, we can quickly and efficiently implement customized solutions – precisely tailored to your testing task.
