Reviews: Fluke 77 IV Digital Multimeter

Rated 5 out of 5 by from Highest Quality, unreal longevity So I worked at Fluke as a designer in the 80's and brought home a 77 prototype. I moved on to another company in '85 but have kept that DVM since. It's been dropped many times and I've gone through I think 3 or 4 9v batteries and it's still going strong after 35 years. Fluke had a robust qualification process that included temperature, humidity, shock, EMI and vibration abuses. When it's time I'll upgrade to another Fluke but I think this one will outlive me.

Rated 1 out of 5 by from Auto OFF SUCKS! You have both hands involved in what you are doing, look at the meter to start adjusting, and it shuts it self off! You loose your set up as you need to move a hand, NEVER WILL I BUY A FLUKE AGAIN!

Rated 5 out of 5 by from Solid meter with great performance. Bought this meter about 6-8 months ago and haven't had any issues. Replaced my old 77 series with this and the newer version is a definite upgrade as it should be. It's voltage range suits well for plc, electronics, and automated service circuit systems troubleshooting. Well suited for field technicians and mechanics alike. Fluke does not disappoint with its rugged package And true test to the elements. I have other meters And nothing is as reliable as my Fluke.

Rated 5 out of 5 by from 77IV Multimeter I purchased this meter several months ago and it has been a pleasure to use. It is easy to understand, the display is easy to see, and the tone is loud enough for me to hear. Excellent, durable product.

Rated 5 out of 5 by from A great General Purpose Meter If you only can carry one meter for general work, this is the one to have. Don't waste your money buying throwaway meters over and over again, when you can buy just one of these and use it (almost) forever .
