Klein Clamp Meters Buying Guide
Respected as circuitry and telecommunication tool experts, this company has become renowned for its durable, accurate, and reliable machines — available at price points that aren’t going to hurt your bank balance or company bottom-line.
And, with a vast range that covers everything from first-time users through to high-energy electrical specialists — there’s a clamp meter suitable for every application, frequency of use, and operator experience.
The Klein Tools Brand
Its first tools were wire cutters for telegraph linemen. These products were so popular due to their robust build and ease of use, that they simply became known as Kleins in the industry — a genericized trademark that remains to this day.
With a foot in the telecommunications door — over the years the brand expanded its range, delivering a plethora of hand tools for telegraph technicians. And, as the telegraph industry evolved into telephone and wide-use electrical businesses — Klein adapted its product range to service these rapidly expanding markets — including safety equipment, wrenches, screwdrivers, and circuit terminal connectors.
This electrical back-history established its focus for the following 160 years — adapting its line-up to match the changing power network.
Today, the business operates out of Lincolnshire, Illinois, USA. In addition to the vast Klein clamp multimeter range — it produces impressive electrical equipment, including digital levels, data and video testers, and laser measurers in addition to their trade-focused hand tools of cutters, knives, and hex keys.
The Klein Clamp Meter Product Range
While the brand primarily focuses on trade-level users, its range also includes DIY-friendly machines for the casual and amateur operative. Yet, due to the pro-centric nature of their tools — it means that the lay-user benefits from the safety, durability, accuracy, and reliability running down from the pro tech.
Furthermore, whether you opt for a contractor-rated or home-focused clamper — you’re assured of affordability. Although many of their testers match premium machines for functionality, they don’t have the high-end price points of similar units from, say, the Fluke brand.
Their catalog includes clamp meters such as the DIY-targeting Klein CL380, the budget CL120, the light-contractor CL700, and the hardcore pro Klein CL800 — all coming with a reassuring two-year manufacturer’s warranty.
