A digital multimeter or DMM is one of the most useful tools that you can have around the house.  The device is designed to measure a variety of electrical matters, and is invaluable for many household and automotive repair processes.
 
Whether you are installing a new light switch or electrical outlet in your home, or testing your spark plugs or alternator in the car, a digital multimeter will prove itself to be a valuable addition to your toolkit, and can measure everything from whether there is a current through an item caused by a loose wire through to whether a battery is charging properly.

Perhaps the best known company who makes digital multimeters is called Fluke.  Based in Everett, Washington, Fluke has been producing high quality scientific and precision measuring equipment for nearly 60 years.  The company was one of the originators of the concepts behind the Digital Multimeter, and to this day produces some of the best models around, making them the first choice for most professionals looking for high quality and robust devices that offer excellent accuracy, and are hard wearing enough to last for years in even the most tricky conditions.

There are a number of Fluke Digital Multimeters manufactured by the company to suit all different budgets and requirements, from entry level devices destined to be used occasionally by people needing to check the occasional product at home, right through to the most accurate meters possible for use in scientific laboratories, and every level in between.

The entry level Fluke digital multimeters are the Fluke 10 and the Fluke 12.  These machines are designed for ease of use and to be hardwearing and good value.  The company does not skimp on quality though, and despite their low price, these home use models still boast impressive levels of accuracy within their normal tolerances.

Fluke also produce a number of multimeters that are specifically designed to meet the needs of anyone involved in working on automobiles.  Their range of automotive multimeters including the Fluke 88V model are specifically intended to be used with the various electrical systems in most cars, and are tailored to accurately measure the at the current and capacitance levels found in an average car.  They also come with specific probes that are designed to get into the cramped quarters within an engine bay to measure components in situ.

At the top end of the Fluke range, are the Fluke 87 models, which offer some of the most accurate and robust, measuring systems available anywhere.  They are able to measure current to within a fraction of a milliamp, and offer the kind of reliability th
