Streamline High-Current Diagnostic Testing with the Bosch PRO GMC600-15

The Bosch PRO GMC 600-15 Digital Clamp Meter is an indispensable diagnostic tool engineered for electricians, HVAC technicians, and commercial contractors who demand speed, precision, and safety. Featuring a rugged, non-invasive current-sensing hinged jaw, this professional electrical multi-tester allows you to seamlessly measure high AC currents up to 600 Amps directly over large conductors without needing to interrupt active circuits. Integrated with advanced True RMS technology, the GMC600-15 ensures highly accurate readings across complex or non-linear electrical loads, making diagnostic fault-finding and routine system maintenance faster and safer than ever before.

Designed to thrive in hazardous, heavy-duty commercial workspaces, this durable clamp meter boasts a robust, rubber-reinforced housing with a drop-protecting ergonomic grip and an IP54 weather-resistance rating against dust and water. The tool delivers superior versatility by supporting voltage ranges up to 600V AC/DC through both its jaw and premium silicone test leads, alongside an integrated high-power flashlight to clearly illuminate pitch-black electrical panels. Packed with ultimate jobsite safety features, including an automatic power cut-off when the battery bay is open and strict CAT III 600V / CAT IV 300V certifications, this compact meter guarantees maximum testing confidence under the most demanding structural conditions.

Key Features

  • Rugged Jobsite Design: Durable over-molded housing with a non-slip ergonomic grip provides impact-resistant drop protection and long-term commercial durability.
  • Non-Invasive High-Current Testing: Extra-large 1.18-inch jaw opening handles thick industrial conductors for immediate current verification without opening circuits.
  • Advanced True RMS Technology: Engineered to provide highly reliable, precise diagnostic measurements on both clean and distorted sinusoidal waveforms.
  • Dual-Source Power Flexibility: Operates universally on standard AA batteries or a specialized 3.7V Lithium-Ion rechargeable battery pack for long-lasting performance.
  • Integrated Panel Flashlight: Built-in worklight brilliantly illuminates dark, enclosed spaces, junction boxes, and complex breaker breaker arrays.
  • High-Contrast Display Visibility: Features an inverted LCD screen that ensures crystal-clear readability under sunlight or inside dimly lit mechanical rooms.
  • Power Cut-Off Safety Protection: Preventative safety mechanism blocks tool activation whenever the internal battery compartment door remains unlatched.
  • Ergonomic Data Hold: Convenient side-mounted button allows simple one-handed operation to instantly freeze measured values on the screen.

What's Included

  • (1) Bosch PRO GMC 600-15 True RMS Digital Clamp Meter
  • (1) Set of Premium Silicone Test Leads
  • (2) Standard AA Batteries

Pro-Tip: When diagnosing strange or irregular power drops in commercial HVAC blower motors, clamp your GMC 600-15 directly around a single conductor phase while utilizing the True RMS function. True RMS measures the actual effective current bypassing the harmonic electrical noise created by modern variable frequency drives (VFDs), stopping you from misdiagnosing a healthy motor!

So so small! Not worth $
The images in Amazon are nothing like what the product is. The pretzels and rings are minuscule. My two pit/lab mixes will eat one in about 30 seconds. So disappointment. Not worth the $ for what you’re getting. I tried to return items which are individually wrapped but they do not allow returns on these products. I have not opened any of them and still not able to return. If you have a dog under 15lbs these may work! If you have a large breed don’t bother. I’m so disappointed. Pictures above is the product next to a small milk bone biscuit (for reference).

A Premium Magnesium Powder From A Brand I Actually Trust
Thorne has a strong reputation in the supplement world, and this Magnesium Citrate powder is a good example of why. Magnesium is one of those basic minerals that does more than people realize. It supports normal muscle and nerve function, helps with energy production, contributes to bone health, and plays a role in cardiovascular function. The NIH notes that magnesium is involved in hundreds of enzyme systems in the body, including processes tied to muscle and nerve function, blood glucose control, blood pressure regulation, and bone development. (Office of Dietary Supplements) Magnesium citrate in particular is a form many people use because it is generally well absorbed and can also help with occasional constipation. That is both a benefit and something to respect. If you take too much, it can move from “helpful” to “where is the nearest bathroom” fairly quickly. I would start modestly and see how your body responds. The citrus berry flavor is pleasant enough for a mineral powder. It is not candy, and it does not need to be. It mixes reasonably well and is easy to work into a nightly routine or use when you feel like your muscles are tight, your diet has been less than ideal, or you simply want magnesium without swallowing another capsule. The biggest selling point for me is the brand. Thorne is not some mystery-label supplement company with a pretty bottle and a warehouse address nobody wants to talk about. Thorne says its facility is NSF certified, it manufactures more than 40 NSF Certified for Sport products, and it is used by professional and national sports organizations. (Thorne) Their Magnesium Citrate product page also states that the product is third-party tested and certified to verify what is in the package. (Thorne) That matters with supplements. You are not just buying magnesium. You are buying confidence that the dosage, purity, and manufacturing standards are being taken seriously. Thorne usually costs more than bargain brands, but with supplements, cheap is not always the victory it looks like on the front end. Overall, this is a high-quality magnesium option from a brand with real credibility. I like it for muscle support, general wellness, bone and heart-health support, and occasional regularity. Just treat it like a supplement, not a snack, especially if you are sensitive to magnesium or already taking other products that contain it.

Taste is good, reliable manufacturer
Thorne is a reputable brand that has come out with a magnesium citrate and has been certified by a third-party. I sometimes wonder about supplements online, but having a third-party certify the product gives me more peace of mind. It comes in a double protected container for further peace of mind. This magnesium citrate comes in a powder form and mixes fairly easily with cold water. There is bicarbonate in the product, so it has a slight bubbly texture. This really tastes like citrus berry and is sweetened with monk fruit extract. I like that it has no artificial sweeteners in it. Magnesium has been known to support muscle heart bone and the urinary tract. It can also help with constipation. My husband is a nurse and he says that they regularly administer this in the hospital when a patient has trouble with constipation. The recommended dosage is one scoop to 6 to 8 ounces of water. There are about 60 doses in the container. If taken once a day, this will last for two months. This is a good alternative to other magnesium supplements. It is a form that is usually well absorbed by the body. Given the reputation of the manufacturer, the ease of use, the benefits, and the ease of absorption, I can recommend this product if you are looking to increase magnesium in your diet.

Certified quality magnesium citrate
If you like powdered supplements and planning to take magnesium citrate, then this one if for you. I take it towards the end of the day, and in addition to the many benefits of magnesium, it actually helps me relax and sleep better, although those are not the main benefits of citrate. I guess we all react differently to supplements. My favorite setup is when I take it in the evening and sip on it during a sauna session. In all cases, I target end of day. The taste is very good and it mixes easily with water. Also, Thorne is a brand I trust and it's certified by various bodies. It's worth the premium but it's better to catch a deal on amazon or add it to subscribe and save for a discount if you're planning to use it long term.
