Klein Tools ET600 Megohmmeter Insulation Tester Multimeter

I recently had the opportunity to use the Klein Tools ET600 Multimeter, Megohmmeter in my line of work, and I must say, it's a fantastic tool, especially when considering the cost compared to its competitors, like the Fluke models. Cost Efficiency: The ET600 is priced significantly lower than the Fluke versions of megohmmeters, which is one of the primary reasons I chose it. Despite the lower price point, this tool does not compromise on functionality or reliability. For professionals or hobbyists mindful of their budget, the Klein Tools ET600 provides substantial value. Performance and Features: The Klein Tools ET600 has proven to be exceptionally reliable for testing electric motors and electrical insulation. It has all the necessary features expected from a high-end multimeter and megohmmeter. The device is intuitive to use with clear readings and robust build quality, which is crucial for frequent, rugged use. Practical Application: I recently used the ET600 to diagnose a problematic 220v 3-phase motor that had a challenging short. The multimeter was instrumental in pinpointing the exact nature of the issue quickly, which saved a lot of time and potential cost in motor repairs or replacement. Its accuracy and reliability in such a critical task were truly impressive. Ease of Use: Klein Tools has done a great job in designing this multimeter to be user-friendly. It features a clear display and straightforward interface that make it accessible even for those who might not be experts in electrical engineering. The setup is simple, and measurements are easy to read and understand, which enhances efficiency in any task. Overall Experience: In conclusion, the Klein Tools ET600 Multimeter, Megohmmeter is an excellent choice for anyone in need of a reliable, cost-effective solution for motor testing and electrical troubleshooting. Its performance is on par with more expensive units but at a fraction of the cost. Whether you are a seasoned professional or just starting out, this tool will meet your needs and exceed expectations. For its price, performance, and reliability, I highly recommend the Klein Tools ET600. It's a worthwhile investment that offers both savings and professional-level functionality.

Tested and used with great success. This is an excellent, accurate tool for its intended purpose, at a fair price and definitely comparable to more expensive meggars.

Specs are exactly as described. It works very well for insulation resistance testing and measures insulation resistance up to 4000MΩ at 125V, 250V, 500V, and 1000V DC. Comes with CAT III/CAT IV Safety Rated Test Leads, Heavy-duty Alligator Clip Test Leads. Bright Easy to Read and understand display.

Great, accurate and inexpensive. The best budget megger in the market. Great to check inverter compressors on hvac systems. All of our tech managers have one.

Great, reasonably priced meter. 1kv megger, true RMS, resistivity, continuity, 1kv tester all in one package. A bit on the heavy side, but has a nice rear angled support.

Excelente producto. Recomendado

The Klein ET600 feels rugged right out of the box—rubberized housing, drop‑safe, and a clear backlit display. As a everyday TRMS multimeter it covers the basics (voltage, continuity, capacitance) with quick, auto‑ranging response, but the real win is the built‑in insulation tester: selectable 125 V, 250 V, 500 V, and 1000 V outputs let you verify motor windings or cable runs without hauling a separate megger. Test‑lead shields and an audible alarm add safety, and the hold/max features simplify logging. Only downside is the 4000‑count resolution, which is fine for field work but less granular than lab‑grade meters. For electricians who need a single, tough tool that handles both standard measurements and insulation resistance, it’s excellent value. I use this unit to mainly test SR trace heat cables, and I have taught many others how to perform these tests with this unit. It's ease of use has been very helpful for this mission. Thanks Klein!

I use this for in floor heat installation and it works as advertised. It is fairly intuitive and easy to understand. Plugs and terminals seem to have good lockup and seem to be of good quality.

Excelente producto, muy recomendable

Great value, solid build, does the job.

Works great! For the price, can't go wrong. If you do any electrical service work, this can help find issues your standard multi meter will miss. Recommended

I’ve had a fluke and I would say I prefer the Kline to the fluke. This Kline et600 has everything you really need, except amperage. The continuity buzzer is good in my opinion, I work in houses mainly and it’s plenty loud for me but if you are in louder environments you may find it hard to hear. The resistance, voltage, and insulation tests are all easy to read and accurate, I’ve checked many heaters, motors and valves and the klines always given the reading I would expect. The meter itself is very tough and I would say atleast as well built as the fluke I had. It feels like a quality tool- and I would definitely choose Kline tools based on this machine for future purchases.

The Klein Tools ET600 Insulation Resistance Tester delivers exceptional accuracy and reliability, making complex electrical insulation testing both fast and straightforward. Its large, backlit LCD display provides crystal-clear readings even in poorly lit job sites, while the dual-function capability seamlessly measures both insulation resistance and AC/DC voltage. Built with Klein's signature rugged housing, it handles harsh job site drops and daily wear without skipping a beat. It is a professional-grade, high-value instrument that provides total confidence when testing motors, cables, and heavy equipment.
