100 Amp Digital Meter and Shunt

Keep all the heavy wires for the amp gauge from your hho kit under the hood (with the Shunt) and only run small wires to the meter inside the cab. Safer and easier, and looks nicer too. Much more accurate than the analog gauges that have a tendency to burn out all the time.We have tried a bunch of meters but we like this one a lot. Even has a small adjustment screw in the back if you want to fine tune the reading using another meter. Exposed back/circuit board- you need to mount in a box or in a hole cut into an access panel. Easy to install. Comes with a clip on wire harness that attaches to the meter. Rated at 9 - 30 volts for powering it up, and rated to 100 amps, so it can accurately keep track of the current your hho generator is running at, and can be used wit 24 volt hho systems.   Shipping All orders over $100 within the U.S. qualify for FREE SHIPPING!
