Precision Power Testing for Demanding Electrical Work – Built for Pros Who Need More Than Just Voltage

The Klein Tools CL900 Digital Clamp Meter is a rugged, auto-ranging TRMS tester designed for high-performance diagnostics in residential, commercial, and industrial environments. With the ability to measure up to 2000A AC/DC current and 1000V AC/DC voltage, this meter is ideal for troubleshooting large systems, motors, and panels. The integrated Low Impedance (LoZ) mode helps eliminate ghost voltages, while the Inrush Current capture mode ensures accurate startup readings. A built-in non-contact voltage tester (NCVT), backlit LCD, and CAT IV 600V safety rating make this meter a reliable companion for electricians and technicians working in low-light or high-risk environments. Whether you're testing continuity, frequency, capacitance, or diodes, the CL900 delivers accurate results with intuitive controls and durable construction.

Excellent value for an automatic watch, keeps VERY good time.
Color: Grey, Color: Grey
I've only had the watch for a day but wanted to leave a quick review on it to share a couple of notes. So far it keeps VERY good time, better than any of the automatics I own (including a Rolex Submariner, Tag Heuer Aquaracer, Tag Heuer Formula One, and several other sub $1k watches). I set it to an atomic time app on my phone yesterday and 24 hours later it's still SPOT on - hasn't gained/lost even a 1/10 of a second. I was shocked to see it's kept PERFECT time for the last day, I'm really blown away so far. I've worn it the entire time, we'll see how well it keeps time while being stored in a winder. This picture shown is the watch with a 22mm leather band on it, fit's without any issues (just need to squeeze in the leather a tad). I doubt it would work with a 22mm metal bracelet, but leather works great. Just FYI since the 21mm lug width is kind of odd. The face isn't quite a lustrious as the images make it look, but it's still a great-looking watch. For a sub $1000 automatic you can't go wrong, this is a fantastic watch at a great price. It'll be my daily driver for some time I'm sure. If I have any issues in the future I'll update the review.

It looks really cool and striking.

Really cool and beautiful watch. Although my specific unit runs 5 seconds fast every day—at first it’s annoying, but eventually you stop caring. 🤣

A Beautiful Timepiece at an Awesome Price!!
Color: Grey, Color: Grey
I have lusted after this watch for four months. I first tried on a similar model (stainless steel band with a green face) in a local jewelry shop (Spitz Jewlers, Walnut Creek, CA, USA). It was "love at first sight," even if I didn't love the white lines on the face from 12-6 and 3-9. At the time, the MSRP was $775. The MSRP has since increased to $795. But I bought this beauty on Amazon.com for only $524.99; after applying the cash-back from my Prime credit card, this watch costs only $498.75. This was "the offer that I could not refuse," to quote from "The Godfather." Accuracy could be better: after only a few days, it is now 7 seconds behind my phone (to which I set my new watch). But I don't really care about that all that much. This is why I rated "accuracy" at 4 stars, but my overall review is 5 stars. My video shows the date changing suddenly at 11:59:59pm, just how I want it; in another photo, you can see that my Seiko changes the date more slowly, which I do not like. This watch is absolutely phenomenally beautiful. If you're on the fence over whether to make this purchase, then I would say "go for it!" You will not find a prettier, more accurate watch at a lower price in ANY store in the entire USA.

Classy and sporty. Great value!
Color: Grey, Color: Grey
Excellent watch for the price. Looks sporty and dressy. More towards dress watch. Blue is dynamic. Strongly recommend blue for sporty feel. I was thinking of aqua terra. This come close to it with a price less than what i would have paid my state tax for omega aqua terra. My only concern is bracelet which i feel kind of OK. Better bracelet design would have made this watch much superior. 21 lug width is awful. Other than that, nothing to complain.
