What To Consider When Buying A Multimeter For HVAC

When you are looking to buy a multimeter for HVAC, there are many things that you should consider.

Single-phase or three-phase

The first thing to consider is whether or not you want a multimeter that runs on a single-phase, three phases, or both. Single-phase power is the most common type of electrical supply in North America and Europe, while three-phase power has been used in Asia and parts of South America.

Single-phase meters have a single power cord and display readings for both current voltages. Three-phase meters will need to be plugged into three separate cables to work correctly, but they are often more accurate than their single-phase counterparts because of how the circuits are configured.

Handheld or probes

The next thing you should consider is whether you want a handheld multimeter or one with probes. Handheld meters will have all of the components necessary to measure current, voltage, and resistance built into them so they can be held in your hand while readings are taken. Probes require an individual to hold only one probe for those values to be read on the meter, but they are more accurate and easier to use when the circuit is large.

LED Backlight

The next thing to consider is whether or not you want a multimeter with an LED backlight. This will allow the meter to be used in darker locations, and it can help make reading values much easier on dimmer circuits.


The last thing to consider is the features of the multimeter. Some may have additional functions like RS-232 interface, PC compatibility, or a thermometer probe, while others are basic meters with no extras. The meter’s features may also affect its price, so it is best to research what you want before purchasing a multimeter.

You must consider what type of work you do before deciding on which multimeter will be best for your needs because they can vary greatly depending on how often it will need to be used, just as with any other piece of equipment. Once you have decided, look at the best multimeters in this blog post to see which one will work for you.

Frequently Asked Questions

Do I need a true RMS multimeter?

You can use it to find out if there are any short circuits in your electric circuit, for instance. When you buy a true RMS multimeter, you’ll get an accurate reading on all three measurements: Voltage (V), Current (I), and Resistance (R).

What does RMS stand for on a multimeter?

RMS stands for Root Mean Square, a mathematical way of calculating power in an alternating current circuit. This calculation can be done using the formula P=AV^2/Z, where A is the waveform’s amplitude (or height), V is voltage, and Z is impedance.

How do I use a multimeter to check a temperature sensor?

The first step is checking the multimeter’s current setting with one probe on each contact point of the circuit board. Next, place probes on either side of the temperature sensor and take note of whether there is any voltage difference or not. If there is no difference, check for continuity by placing one probe on each end of the wire connecting them.

Can we measure temperature with a multimeter?

Yes.  However, if you measure temperature with a multimeter be sure to use the correct type of probe. Two types can be used for this application: an analog type and a digital type.

The analog probe has a round metal tip that will not measure accurately because it picks up too much heat from the measured object, causing an inaccurate reading. You want to use the digital type, which has either one or two flat probes on a wire stem that should touch only one side of the object being measured for accurate readings without picking up any excess heat from other areas nearby.
