Brand Backgrounds: Ideal And Klein
Understanding a company’s history gives insight into why their tools are trusted (or not) on job sites. Both Ideal and Klein have deep roots in the world of tools, but their stories and focus are a bit different.
Ideal Industries
Ideal Industries started in 1916 in Illinois, USA. From the beginning, Ideal focused on making tools for electricians. Their first product was a wire nut connector, and over the years, they’ve become known for reliable, affordable electrical test equipment. Ideal targets professional electricians but also makes products for students and home users. Their reputation is built on solid construction and practical features that meet the needs of working pros.
Klein Tools
Klein Tools is even older, founded in 1857. Klein’s reputation was made with hand tools like pliers and screwdrivers, but they have expanded into test equipment over the past few decades. Many electricians grew up using Klein hand tools, so there’s a trust factor built into their multimeters. Klein emphasizes ruggedness and job site durability. They design tools that can survive drops, dust, and rough use.

Advanced Features And Usability
A basic multimeter will help with simple tasks, but advanced features can make complex jobs much easier. Here’s where Ideal and Klein show their strengths and weaknesses.
True Rms Measurement
True RMS is critical for accurate readings on modern electrical systems, especially when measuring non-sinusoidal AC signals (common with variable speed drives or electronics).
- Ideal Multimeter: Most mid-range and higher models are True RMS.
- Klein Multimeter: Nearly all professional models are True RMS.
Non-obvious insight: If you work in industrial or commercial settings, skipping True RMS can lead to incorrect readings that may cause troubleshooting headaches or even damage.
Non-contact Voltage Detection
Electricians love non-contact voltage detection (NCV) for a fast check if a wire is live.
- Ideal: Some models include NCV, but it’s not standard on all.
- Klein: Most newer models include NCV or have it as an extra feature.
Temperature Measurement
Some jobs require measuring temperature, for example, HVAC troubleshooting.
- Ideal: Select models have a thermocouple input.
- Klein: Several models include temperature probes and can display °F/°C.
Tip: If you do HVAC or industrial maintenance, consider a model with temperature measurement built-in.
Backlight And Display Quality
A good display is more than just a convenience. If you work in dark panels or outdoors, a backlit, high-contrast display saves time and reduces mistakes.
- Ideal: Good backlighting on most models, digits are large and easy to read.
- Klein: Klein displays are usually bright, with some models offering bar graphs that quickly show signal fluctuations.
Build Quality And Ruggedness
Tools get dropped. They get dirty. A multimeter that breaks after one fall is not worth your money.
- Ideal: Most meters have a solid plastic case and good impact resistance. Test leads are thick and flexible.
- Klein: Known for rugged construction. Many models meet drop-test standards (often up to 2 meters).
Non-obvious insight: The quality of the test leads is just as important as the meter body. Cheap leads can break, give false readings, or even cause injury. Both brands include good leads with mid- and high-end models, but Klein often has thicker insulation.
