Except for safety and reliability, which are the main two things that a technician should be looking for when searching for the best HVAC multimeter, there are plenty of other specifications that make a good device. Although multimeters that are being used by HVAC specialists are much like regular ones, they have extra specs such as the ability to measure temperature and detect potential leaks. Also, it is important to be able to be notified, either visually or audibly while measuring continuity, for instance. Being able to read 1/10 of a microamp, having a capacitor tester, auto-ranging and non-contact voltage tester are considered a huge plus.
In an electrician’s eyes, the quality of a multimeter resumes to three things: durability, functions and price. Nowadays, you can find plenty of products that combine all of the advantages and even more. There are a few features that are not essential, but make a technician’s work easier and more comfortable. Some of those can be the existence of an LED flashlight, a backlit scale, a surface mount temperature probe, true RMS meter, functions that eliminate ghost voltage etc. If you are just beginning to understand how multimeters work, focus on the models that have intuitive controls, easy to use functions and comprehensible instructions. If, on the other hand, you are an advance multimeter user, focus on the device’s capabilities and durability rather than on the design.
