Innova Automotive Multimeter

Review
The Innova 3340 Automotive Multimeter comes with an inductive RPM clamp and carrying case, but that’s not all! It has a 10 megaohm impedance to help prevent damage to the ECU, automatic zero adjustment, overload protection, and reverse polarity protection. You can check on temperature and RPMS as well as test diodes, continuity, duty cycles, pulse width, and more. It measures up to 600V AC/DC, resistance to 40 megaohm, DC current to 15A and AC to 400 mA, and frequency to 2 MHz. Narrow down the type of data you’re collecting with the min/max and hold buttons. Rubber corner guards act as shock-absorbers for bumps and drops, while overload protection and reverse polarity protection absorb a different type of shock! This is one of the best cheap autoranging multimeters you can find and should work well for electrical troubleshooting around the house as well as in your garage.

Actron Automotive TroubleShooter

Review
The Actron Automotive Troubleshooter CP7677 is a digital multimeter and engine analyzer with an extra-large LCD screen and protective boot to handle accidental drops and bumps. It measures resistance up to 20 megaohm, DC volts up to 1000 mV, AC up to 750V, and DC amps up to 10A. It also includes dwell for four, six, and eight-cylinder points-type ignitions, tach for checking RPMs, and continuity testing with an audible alert. Other features include automatic zero adjustment for volts and amps, overload protection, and automatic reverse polarity indication. The dwell test option is a must-have if you’re maintaining vintage pre-1970s automobiles. This is one of the best multimeter options if you’re on a budget--manual range multimeters tend to be less expensive than auto ranging multimeters. You can do a ton of automotive problem-solving with this multimeter, including testing ignition and fuel delivery, plus starting and charging, and locating wiring issues and busted sensors.

KKmoon Automotive Multimeter

Review
The KKmoon Automotive Multimeter comes with test leads, a temperature probe, and alligator clips to get you started off right. It can measure AC/DC current to 20A, AC voltage to 700V, DC voltage to 1,000V, resistance to 200 megaohm, temperature, hFE (current gain), and capacitance to 200 uF. You can also use it for testing diodes, continuity, and duty cycles as well as dwell and tach (RPMs). Dwell is an important feature if you work on points-type ignition systems, which are most often found in pre-1970’s vehicles. You can use the tach setting to check RPMs on other vehicles as well. Note that this multimeter lacks auto ranging, so if you’re working on cars every day, you may prefer autoranging for taking measurements more quickly. For auto hobbyists and homeowners who need an inexpensive multimeter for troubleshooting, that shouldn’t be an issue. It’s a great automotive multimeter with an incredibly low price to boot!

HONGDA Automotive Multimeter

Review
If you have a vintage pre-1970s vehicle, chances are it has a points-type ignition system that needs to have the dwell angle checked periodically. If that’s the case, this multimeter from HONGDA allows you to do so! For “younger” vehicles you can use the tach feature to get RPMs as well. It also measures AC/DC currents to 20A, AC voltage to 700V, DC to 1000V, temperature, and capacitance to 200 uF. Note that this multimeter lacks a frequency testing option, which can come in handy when you’re dealing with some types of sensors and signals, such as speed sensors and fuel injector control signals. Alligator clips are included as well as basic leads to get you started! A multimeter that can help you check the dwell angle is crucial to maintaining vintage automobiles. You can also test diodes and check continuity with this multimeter, so it has a lot of applications!

Tacklife Advanced Multimeter

Review
The Tacklife Advanced Multimeter takes your electrical work to the next level by making it easier to take various measurements. This clamp-style multimeter can measure AC/DC current from the outside of a conductor--no need to expose wiring to take a measurement! It also has Non-Contact Voltage (NCV) detection and a live line test with buzzing alerts and flashes to let you know when you’ve got a live one (any AC voltage between 90-1000V). It has a backlight and flashlight option as well for better visibility in any environment. It measures AC/DC voltage to 600V, current to 400A, resistance up to 40 megaohm, and capacitance up to 100uf. The continuity test sounds a buzzer if it measures resistance under 50. This is a strong contender for the best multimeter for cars and home use thanks to the NCV and clamp features on top of its other measurement abilities.

DKMHA Digital Multimeter

Review
The DKMHA Digital Multimeter can be set to auto or manual ranging to make taking measurements faster. It can be used to test resistance up to 60 megaohm, DC voltage to 600V and AC to 700V, AC/DC current to 20A, diode testing, and continuity testing with an alert buzzer. You can also use it to take temperatures, like if you’re worried your new sound system is getting too hot! The LCD display has a backlight you can toggle for low-light conditions in your dim garage, and it has a reinforced plastic shell for protection against accidental drops and grease. The multimeter comes with test leads and a thermocouple that will come in handy if you ever need to test your car’s heating and cooling systems. You can store readings to look back on them and easily compare, and a low battery indicator lets you know the status of the two AA batteries. This multimeter is a great option for helping you troubleshoot and maintain your vehicle.
