Amprobe RS-3 PRO CAT IV 300A Analog Clamp Meter

This CAT IV 600V safety rated analog clamp is a great tool for tough electrical applications. The RS-3 PRO works well in extreme temperatures from 32°F to 122°F, while digital clamp LCD screens tend to freeze this anolog clamp measures up to the test. The RS-3 PRO does not require batteries for measuring Amps and Volts and shows measurement with an easy-to-read rotary scale.

Amprobe RS-3 PRO CAT IV 300A Analog Clamp Meter is rated 4.9 out of 5 by 21.
Rated 3 out of 5 by from bulky for no good reason twice as big as old RS-3 I want to replace. No good reason for added bulk.

Rated 5 out of 5 by from The value of an analog ammeter I use mine for checking variable frequency drives, sequencing motors, etc... The digital signal will give a needle bounce on the analog meters. Digital meters will just autorange and will be useless to you. The analog will detect an open phase by watching the bounce. When there is a bad leg on a 3 phase system one of the legs will bounce twice as much, to make up for the missing leg. This imbalance tells you there is a problem. The fact that it is a clamp on keeps you save and makes detection fast. I love this meter. Never do away with the analog!

Rated 5 out of 5 by from This meter is safe, relaible and user friendly I am writing to review and reccomend the Amprobe RS-3 Super analog V-O-A meter. I have used this meter on a daily basis for many years as journeyman electrician doing service and troubleshooting work and I trust the meter for it's accuracy,conveient size, & it's reliability. The RS-3 Super is my choice over digital models. I like the simplicity, user friendly size and clarity of reading measurements being taken. I am now in a position to demonstrate its use to apprentices and fellow journeyman & I enthusiastically reccomend this great product to everyone.

Rated 5 out of 5 by from Simple to use, Helps keep me safe, Extremely dependale Hard to be brief regarding my Amprobe Analog RS-3 Super clamp-on meter. It didn't take long in the trade (started many,many years ago)to give up the "wiggie" for a meter that was much more versatile and actually safer to use. My meter was furnished to me by my contractor after me insisting that I needed this meter since I was doing troubleshooting for him. I could write a book about the many times I reached into my tool pouch for my "amprobe". I am now retired but not out of the trade. I'm the Training Director for our local JATC and in this capacity I have an opportunity relate to all of our apprentices and JW's the value of having the right test meter available always. I still have my RS-3 analog clamp-on to "show and tell" them how valuable this meter is as well as all of the amprobe products avilable for wireman. I'm very happy to reccomend this meter for sure. I want to see a "needle deflection" not some digitized number appear on a meter, not actually knowing if the thing is working properly or maybe the battery is dead or something. Thanks for the opportunity to express my thanks for making not only this product, but the many fine products that you do. "told ya", hard for me to be brief!

Rated 5 out of 5 by from Must have meter I am retired from the HVAC business. For 30 years I used the rs-3 meter for all my electrical needs to preform tests on all types of a/c and heating equipment. Volts, amps and continuty readings. I had tried other meters and just found that I had more success with this meter. Idid and still do recomend this meter to everyone in the HVAC business! Thanks

Rated 5 out of 5 by from Best of the best As an ex electrical contractor I have used Amprobes for years. My favorite over thes years was my trusty old Amprobe Jr. It offered the ease of use and accuracy of it,s big brother, plus the added advantage of it,s compact size (about half the sise of the others) that made it a welcome addition to my ever present tool pouch.
