D/C Voltage Probe & Diagnostics Tool


  • Available in 12 and 24 volt versions

Product information

At first glance this low cost D/C voltmeter looks like any other one available anywhere, however, on close inspection you will see it is not. Standard voltage probes only go to 14 volts and are unable to inform you if the advanced charging cycle is in progress or a system has failed and is overcharging your system. The extra two LEDs re preset to give more useful information than the very limited standard ones. This is a Sterling product and is not available anywhere else.

Wind Up Multimeter

Do you ever find yourself needing a multimeter , which you know you have somewhere and when you find it the batteries are flat, well never again, this new product has no batteries so you can leave it as long as you like, simple wind the handle 2 times for about 2 mins use, winding for about 10 seconds will give about 10 minutes of use. The high quality extremely well equipped with all the features and functions required for general use.
