Great multi meter

“I recently purchased the Klein multimeter, and it has quickly become one of my favorite tools. The build quality is solid, and it feels durable enough for both professional and DIY use. The readings are precise and reliable, whether you’re measuring voltage, current, or resistance. The display is clear and easy to read, even in low-light environments, thanks to the backlight. It also has an auto-ranging feature, which makes it convenient for switching between different measurement tasks without needing to adjust settings manually.Another standout feature is its safety – it feels well-insulated, and the leads are sturdy. The battery life is impressive, and I appreciate the built-in stand that allows hands-free use. For the price, it offers excellent value and performance. I’d highly recommend the Klein multimeter to electricians, technicians, or anyone needing a dependable, accurate tool for electrical work.”

Well made meter

Works well I use for commercial refrigeration and it gets the job done screen is easy to read back light helps in the dark battery’s last a long time storage is easy size is just right

Features and Comparison

This is a great meter in terms of form and function. The exterior is very durable. The plastic parts seem very sturdy and there is a rubberized coating on the sides as well as on the dial. The dial and buttons are firm and feel like they are very good quality.I'm not an electrician, I flip houses for a living. I have an occasional need for a meter to test an HVAC capacitor, the continuity of a fuse, a faulty breaker or my car's alternator. I owned a Klein MM6000 about a year ago for a very short time. It seemed like a fine meter and worked well but I was hung up on owning a Fluke as they are known to be the best in the industry. I tend to gravitate toward the best of the best when I buy anything as there is so much crap out there. Since I didn't have much of a need for a meter at the time, I returned the MM6000 and started researching Fluke to determine which one I wanted to buy. Needless to say it has been a year and I just ended up with the Klein CL800. The main reason was price. I paid $120 on Amazon for this meter and it's features are equivalent to Fluke's that cost $300-$500. I would say the features contained in this meter are closest to what you would get with a Fluke 375 or 376 which are $329 and $468 respectively. Obviously the most important thing with a meter is that it is accurate. The specs on this meter, according to the data sheets, appear to be on par with many of the clamp meters from Fluke.This meter has so many great and convenient features. First of all it is TRMS. It tests AC/DC voltage to 1000V and AC/DC amps to 600A, and also handles millivolts. It tests continuity, capacitance, diodes, resistance, frequency and temperature. It has a setting for low impedance, it has a flash light, a back light, hold button, min/max, range, and a non-contact voltage tester. The non-contact voltage tester lights a red light when there is voltage present but there is no tone and it works from approximately 6 inches from a power source such as a light switch or outlet.Some of the things I specifically like about this meter are the fact that it has one setting for volts and one setting for amps and you use the select button to switch between AC and DC. This meter will also measure millivolts but there is no extra setting. You simply set it to measure volts and it will auto range appropriately. I also like the flashlight and the non-contact voltage tester. Most of the Flukes don't have either of these features.There is nothing about this meter that I don't like. I will mention a couple of things that changed from the previous models of the Klein clamp meters to the new ones. The previous models included an audible non-contact voltage tester, slots in the rear of the meter for lead storage, the previous models included a bar graph which this one does not, and the included leads are of lower quality and do not come with alligator clips included. These features would have been nice additions to this meter but are very minor in the scope of what this meter does.I would have to say this is a great meter for only $120.

Very happy with this meter!!

I wasn’t expecting a lot out of a $120 meter when I purchased this Klein CL800 but I am writing this review to tell anyone considering it that it is in my opinion the best value for your $$. I’m a Journeyman Wireman of 10 years and have used this meter off and on for the past 2 years in industrial, commercial and at home automotive work. This is a tough well built meter that provides accurate measurements even when compared to my Flukes. Also it has the most amount of different testing capabilities you can find in a clamp meter from testing capacitors and diodes all the way temperature as well as your standard Volts (A/C and DC) Amps and continuity. I have been very impressed with the quality, accuracy, and dependability of this meter. I don’t think you will be disappointed as a homeowner or commercial/industrial electrician.

Great way to check your RV Batteries

Bought this for an RV Class and still use regularly. Well made and effective.

Very useful for an electrician

I have had three similar to this before, the CL2200's. One lost, one stolen, one my dogs carried off somewhere. This last one has a few more features which I have not used yet such as temperature.The negative on this one is it does not have a built in magnet, But they sell one that attaches to it which can be used in more ways, and which I bought and always have attached as I use the magnetic hanger practically every time I use the device. But the hanger is often in the way but can be dealt with. I would not be without it.The LoZ function is the main reason I bought this model. I often have to determine whether the voltage I am seeing is real or ghost and this does that. However, the old Klein or Square D solonoid wiggy will do that faster with more accuracy than this one does.It has a very usable light which is easy to turn on, both AC and DC volts/amps, and mini volts and mini amps. Plus all the other features which you will see in the advertisment such as continuity, diode, capistance, temperature, and resistance ohms.Very useful well built tool which performs as well or better than most fluke products at a much lower price.
