Accelerate Commercial Electrical Diagnostics with the Bosch PRO GFM1000-15

The Bosch PRO GFM1000-15 Professional Fork Meter is a revolutionary diagnostic solution engineered to accelerate system maintenance for electricians, facility technicians, and HVAC contractors. Featuring an open-jaw design, this powerful electrical tester enables non-invasive AC current measurements up to 200 Amps directly over conductors without breaking active circuits. Seamlessly integrated with high-performance True RMS technology, it accurately interprets distorted waveforms on complex commercial equipment, allowing for swift and reliable fault-finding in tight, high-density distribution environments.

Built for survival on demanding jobsites, the GFM1000-15 features a rubber-reinforced housing that is field-tested to withstand accidental drops from up to 6 feet and is protected by an IP54 dust and splash resistance rating. This all-in-one instrument records AC/DC voltages up to 1000 Volts and integrates specialized features like low-input impedance (LoZ V) to automatically eliminate phantom ghost voltages. Complete with a built-in non-contact voltage (NCV) detector, an integrated LED panel flashlight, and an uncompromised CAT IV 600V / CAT III 1000V certified safety rating, it delivers ultimate field confidence and reliable one-handed usability.

Key Features

  • Rapid Non-Invasive Diagnostics: Open-fork jaw design captures fast AC current measurements without lead connections or circuit interruptions.
  • Advanced True RMS Accuracy: Engineered to provide highly reliable, precise electrical readings on non-sinusoidal waveforms and active variable loads.
  • LoZ ghost Voltage Elimination: Low input impedance mode filters out misleading ghost voltage readings across adjacent live wiring runs.
  • Rugged Heavy-Duty Architecture: Rubber-molded ergonomic grip resists jobsite abrasion, drop-tested up to 6 feet with an IP54 weatherproofing rating.
  • Dual-Source Power Versatility: Operates universally on standard AA batteries or a professional 3.7V Lithium-Ion rechargeable pack for diminished downtime.
  • Integrated Safety NCV Sensor: Built-in non-contact voltage tester provides fast, audio-visual proximity checks before managing exposed wires.
  • High-Visibility Inverted Screen: Crystal-clear, high-contrast inverted LCD ensures immediate visibility inside unlit industrial enclosures or basements.
  • Premium Safety Compliance: Certified to elite CAT IV 600V and CAT III 1000V safety classes with integrated protective power cuts when battery doors open.

What's Included

  • (1) Bosch PRO GFM1000-15 True RMS Fork Meter
  • (1) Set of High-Quality Flexible Silicone Test Leads
  • (2) Standard AA Batteries

Pro-Tip: When troubleshooting confusing modern lighting ballast setups or commercial HVAC controls, toggle the GFM1000-15 to LoZ mode. This pulls down stray capacitive ghost voltage created by parallel wire runs, confirming instantly whether you are tracking down an actual electrical fault or just a harmless induced field signal.

Not Quite So Durable...
Color: B) Medium 3" Ball, Color: B) Medium 3" Ball
Maybe I have a SUPER aggressive chewer...he went through this ball in under a week. I originally bought the ball because of a review that stated the owner's Pitbull had the same ball for two years; not so much for my Rottweiler. He started chewing off and swallowing small crumbs from the ball within a day or two. By the end of the week, it was chunks so I had to toss it in the trash to prevent an intestinal obstruction. On the up side, my Rottweiler LOVED the ball while it lasted. However, I can't, in good conscience, give this ball a rave review based on this experience. Please take this review with a grain of salt as I have yet to find ANY toy that my boy won't DESTROY in a week or two. I hope that someone finds this informative when searching for chew toys for SUPER aggressive chewers like mine.

loud but in a good way
Size: 4.5"
Love these crazy loud squeeky balls. I bought two a bit too big but the dogs still love them. Yes, they will drive you insane but the dogs love them so much it's worth it watching the pups enjoy the balls. They are strong and safe as long as they aren't too small for your dogs mouth.

Great for aggressive chewers - Great for clean teeth
I never thought these would stand up to my 60lb pittie puppy's chewing. But they are far and away her favorite toy and are holding up beautifully. One squeaker insert bit the dust -- which is not bad since it gives us one silent one. But otherwise they are holding up superbly to her powerful jaws. We have tried a lot of toys. So far, all the "for aggressive chewers" toys have been torn apart within days if we are lucky -- usually it's minutes. But these balls show little-to-no sign of wear. The squeakers are very loud which she loves can get a bit tiresome. So, as I mentioned, having one silent one is a great option. And she really likes the texture. She loves them so much, we bought a second set and will probably buy a third to have in reserve. (We are realistic and don't expect them to last forever.) All I have to say is "where's spiky ball" and she instantly stops what she is doing and goes on the hunt. A great buy!! (NOTE: It's been almost three months and one is just beginning to show some damage. Given that she plays with them non-stop, they've showed amazing durability. And everyone comments on how clean and beautiful her teeth are. I don't brush them or give her dental treats. So it has to be these balls!!)

Good sturdy ball for aggressive chewer
Size: 4.5"
Nice heavy duty ball that my 7 yr old pitbull can chew on and not destroy it in 2 minutes. Wish that could get 3 for the cost but whatever. Nice bright colors . Good size that he won't choke on it .

Great ball but poor squeaked design
Size: 4.5"
My Rottie loves these balls. The ball lasts a long time even though he plays hard and chews them. My biggest complaint is the squeaker disconnects easily from inside the ball, the glue does not hold! We have bought many of these balls because eventually the area where the squeaker is attached comes away from the ball leaving an open whole that causes the ball to eventually developed a long crack at which point it no longer is able to be thrown nor is is fun for him any longer.
