10 Best Hvac Multimeters 2025 in the United States

The Fluke 323 Clamp Meter is a reliable tool for both commercial and residential electricians, particularly in the HVAC field. It measures AC current up to 400 amps and AC/DC voltage up to 600 volts, which covers most basic needs for HVAC work. The inclusion of true RMS technology ensures that you get accurate readings on both linear and non-linear loads, making it versatile for various electrical scenarios.

The meter is designed for durability, meeting IEC safety standards and rated for CAT IV installations up to 300V and CAT III installations up to 600V, ensuring it can handle tough environments safely. However, it's worth noting that the meter does not measure DC current, which could be a limitation for some specialized tasks. The audible continuity sensor and resistance measurement up to 4 kilo ohms add further utility.

The device is lightweight at 200 grams and comes with a soft carrying case, making it portable and easy to handle. The display is clear and easy to read, although it lacks advanced connectivity features, which might be a drawback for users who rely on data logging and remote monitoring. The product includes a two-year warranty, adding peace of mind. The Fluke 323 offers robust performance, accuracy, and safety for most HVAC applications but may fall short for those needing advanced features like DC current measurement and connectivity options.

The Fluke 117/323 Kit Multimeter and Clamp Meter Combo Kit is designed for both residential and commercial electricians. It includes two essential tools: the 117 multimeter and the 323 clamp meter. This kit is known for its high accuracy, with true RMS technology that ensures precise measurements even on non-linear loads, which is crucial for modern electrical systems.

The 117 multimeter's low input impedance helps eliminate false readings due to ghost voltage, enhancing its reliability. It measures both AC and DC voltage and current, making it versatile for various tasks. The 323 clamp meter also provides true RMS readings and can measure up to 400 A AC current and 600 VAC/DC voltage, adding to its utility in different scenarios.

The kit does lack temperature measurement capabilities, which might be a drawback for those needing this feature. Additionally, it is battery-powered, so keeping spare batteries on hand is necessary. The display is user-friendly and clear. Durability-wise, Fluke is a reputable brand, and the included carrying case and TPAK ensure that the tools are well-protected and portable. This kit is a solid choice for electricians looking for accurate and reliable measurement tools.
