Tough pro tool

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.

Decent

It’s a great meter all together only thing I’d say to be picky is the tone test noise is a little quiet. Everything else is great

High voltage safety at a sensible price

Purchased this as I will be working on High Voltage vehicles (EV and Hybrid), this meter has all the features of others priced at almost double what this one was available at.

Solid device with great safety features

If you’re in the market for one of these you’re probably a professional and need something you can depend on for work. From what I have been able to use this for so far I’m very impressed and it has worked flawlessly. I haven’t tested it to the full 1000v however everything else works well. The unit itself is built well with a solid stand and rubberised surround when holding it. The dial and buttons are easy to use and the screen has large digits easy to see.If you connect something with live voltage it sounds an alarm and gives you the voltage passing through.It comes with the batteries you need 6 AA’S and these are hidden below the stand and can be accessed with a screw driver.It’s a quality item and does everything it promises. Hopefully my review has been helpful.

A professional quality tool for Electrician’s.

This is one heavy duty multimeter. It’s designed for high voltage applications so it’s definitely aimed at the professionals out there. Build quality of the unit is outstanding and it comes with a nice carry case that can hold the multimeter and it’s accessories. The display is large, clear and the backlight makes it easy to see in low light situations.It comes with a fully insulated set of clamps for safety which is just as well when your dealing with high voltage electrics. Accuracy seems great when I tried it out though I didn’t use it with any voltages that were too crazy. It has a built in stand that makes it super easy to use.

Great Megger

This is a solidly-built, reasonably-priced megohmmeter/multi-meter. This piece of kit is handy to check for cuts or voltage loss on wires if you have the knowledge and competency. Anyone flocking out to buy this will know what they are doing so I just cut to the chase, a few cons:-I did not like the connection of the wires to the crocodile clips which looks a little flimsy-The caps that are covering the clips can potentially slip down if not careful-Prefer the testing probes handle in silicone, these are only plasticKlein is one of the leading brands on electrical tools that is affordable and durable. This product is no exception that does what it says brilliantly and it can take a few knocks on the field.
