HVAC multimeters are handy tools for diagnosing heating and cooling systems. Fluke and Fieldpiece are two brands that must be on your radar if you’re searching for the best option. Which is better?
Fluke digital multimeters are expensive, but they are known for providing in-depth testing. Their electric meters are also famous for their durability. On the other hand, Fieldpiece meters are more affordable. They are suitable for regular testing and newbies.
In this article, I’ll discuss two of the most popular brands for diagnosing heating and cooling systems and three of their best-selling models. I’ll compare their features and performance to help you decide which option is better.
Fluke HVAC Multimeters
Fluke is one of the most recognizable brands in the global market for digital multimeters. The manufacturer boasts that all their multimeters can provide accurate measurements and consistent performance. Not to mention, they emphasize safety. Fluke also offers an incredible warranty for your peace of mind.
If I had to choose only one, I would say that Fluke is a better option. They’re expensive, which can put some people off. Because of their price, they are better for HVAC professionals and may not be as practical for DIYers. They have been through extreme tests, so durability is second to none. These multimeters also work well for in-depth testing.
The quality of measurements in Fluke multimeters is notable. They are accurate, meaning they stay close to the actual value, which shows reliability. It also has a good resolution, which is the smallest value the multimeter can display.
And if you need more compelling reasons to choose Fluke, it’s also worth saying that they can handle high-voltage surroundings. You can use it even in industrial environments. Despite such, you must pay attention to using multimeters safely. You must wear protective gear and mind the CAT ratings of your multimeter. All recommendations are available on Amazon.com.
