Compatible with any oscilloscope with high impedance BNC input, the new N2781B current probe offers accurate and reliable solution for measuring ac and dc currents. Using a hybrid technology that includes a Hall effect sensor and an AC current transformer, the probe provides accurate measurement of DC or AC currents up to 150 Arms continuous. The current probe features flat frequency response, low noise and low insertion loss that make the probes ideal for current measurements in such areas like measuring steady state or transient current of motor drive, switching power supplies, inverters, controllers, disk drives, LCD displays, electronic ballast and current amplifier driving inductive loads.
  • Flat bandwidth - dc to 10 MHz, Max. Current 150 Arms
  • Superior 1% accuracy and high S/N ratio
  • Overload protect function prevents probe damage at excessive input
  • Direct connection to high impedance BNC input of oscilloscope
  • "Demagnetize" button to remove any residual magnetism that built up in the magnetic core
  • External power supply N2779A lets you connect up to three N278xBs to a single power supply

Indestructible, but maybe too much?
Color: Orange, Size: Medium
Not too enticing for my dog, but, it is definitely indestructible! He chews on it every so often, but less than I had expected. I think the material is so rock hard that it offers little incentive for him to chew on it.

Best I've Tried
Color: Blue Shark, Size: Medium
With my pitty pup, there's no such thing as an indestructible toy, but this has been the most impressive so far. It's lasted days vs the typical minutes his new toys survive. It has a squeaker, but no fluff, and this has been great. He's been trying to get at if for a long time with no success! He has tore thru the rubber portion, but there's still plenty of play left in this toy. The 3 different textures keep him interested vs the hard material toys he rejects or chews on them too long and I worry about tooth wear. Definitely buying more.

My dogs love them
Size: Large, Style: Peanut Butter
One of the few toys my pit bulls can't break. They absolutely love these toys and play chase with them. Usually, they can break toys in less than 5 minutes, but not these.
