Whether you need an amp clamp for HVAC, general electrical or motor testing applications, the AMP-320 Clamp Meter, with its large backlit display, has the features you need. HVAC technicians will find the temperature and capacitance measurements they need plus DC Microamps for testing flame sensors. It also had core motor testing capabilities such as motor rotation, 3-phase sequence testing, and inrush current measurement for motor start-up monitoring. The low pass filter allows you to accurately measure current and voltage on variable frequency drives. The Amp-Tip function allows for precise measurement of current down to the tenth of an Amp, enabling accurate current measurement of both large and small diameter wires. It also offers a full range of standard multimeter features, including AC/DC current, AC/DC voltage, frequency, True-RMS, non-contact voltage detection, resistance, continuity and a CAT III 600 V safety rating.

AMP-320 600A AC/DC TRMS Motor Maintenance Clamp Meter is rated 4.6 out of 5 by 7.
Rated 5 out of 5 by from Great Bang For The Buck! Lightweight, compact, feature rich, easy to use, ergonomic, durable, quality construction, precise, affordable. All traits that are desirable and included, at no extra charge, with this meter. The Amprobe AMP-320 is a piece of test equipment that feels good in your hands. A tool you can be proud to show off to your buddies with pride. Its no BS precision ensures my safety as well as allows me to get my job done quickly with no guesswork. I wish it were made in the US, but made in Taiwan sure beats made in China in my book. The user manual is well written, with clear illustrations. The extra accessories included were a nice bonus, and much appreciated. I don't know why you are still reading my review. Go out and get one for yourself... now.

Rated 3 out of 5 by from Needs magnet and Lead holder This Meter is a nice meter for the price. It needs a magnet and a lead holder on the clamp to make it above and beyond. The batteries that came in the meter did corroded and died within the first 3 weeks of ownership.

Rated 5 out of 5 by from This product makes my electrical life easier The Amporbe 600A AC TRMS makes my electrical life easier when I am performing electrical diagnostics on HVAC units. Its made to fit well in my hand with no slips. It is esay to adjust to different settings with just my thumb, allowing me to test various components without stopping to use two hands to change settings. Most of all I can trust amprobe to keep me safe.

Rated 4 out of 5 by from Accurate meter This meter has helped me do this job for the last 2 years. I use this product several times a week in trouble shooting. We have two Amprobe's in the company and trust the information we receive from them. The only problem I have discovered is they should have added a timed shut down to save your batteries if you forget to shut off.

Rated 5 out of 5 by from Love this meter! I love how rugged this feels when I'm working. I haven't dropped this one time since I've had it. It's the perfect balance of quality, value, and practical application for my job, and those techs under me that seem to always want to borrow MY stuff... it's economical enough so that I bought a spare that is available for that without giving up my main one! This has all the functions I need, accurate, RMS, etc... I work on HVAC so there's a myriad of measurements that are necessary from day to day.
