Both Fluke and Fieldpiece are trusted by technicians and engineers for accuracy, reliability, and durability. But while they share a similar purpose, their design philosophies differ.
The Fieldpiece SC680 is built specifically for HVACR professionals, while Fluke clamp meters cover a broader range of electrical and industrial applications.
Among Fluke’s lineup, the Fluke 376 FC stands out as the most comparable competitor to the SC680. Let’s explore why these two models are often mentioned in the same breath, and how they differ in real-world performance.
⚙️ Why Compare the SC680 with the Fluke 376 FC?
Fluke produces many clamp meters – from the entry-level Fluke 325 to the HVAC-focused Fluke 902 FC and the high-end Fluke 376 FC. The SC680 aligns most closely with the 376 FC because both are:
- True RMS meters for accurate AC/DC readings
- Designed for high-current measurement (up to 600A and beyond with flexible probes)
- Equipped with wireless connectivity (Job Link vs Fluke Connect)
- Capable of data logging and inrush current capture
Both target technicians who demand precision, connectivity, and advanced diagnostic features.
🔩 Overview of Each Model
Fieldpiece SC680
The SC680 is the flagship clamp meter in Fieldpiece’s lineup, designed from the ground up for HVAC system diagnostics. It measures AC/DC voltage and current, power (kW, PF), and supports dual temperature inputs for simultaneous superheat and subcool measurements.
It connects to the Job Link® System App, allowing technicians to log, trend, and share live measurements from the field.
Fluke 376 FC
The Fluke 376 FC is part of Fluke’s Connect family, built for high-accuracy electrical work. It measures AC/DC current up to 1000A (and even more using the iFlex® flexible current probe). It’s designed for both industrial and residential applications, with CAT IV safety rating, inrush capture, and wireless data logging via the Fluke Connect app.
Its biggest strength lies in flexibility and precision across diverse electrical systems.

⚡ Performance & Usability
Measurement Capabilities
The SC680 focuses on HVAC diagnostics, adding features like power measurement (kW, PF) and dual temperature channels, which are crucial for refrigeration and air conditioning analysis.
The Fluke 376 FC emphasizes electrical performance and current flexibility, using its iFlex® probe to measure around large conductors and tight spaces — a big advantage in industrial or high-power environments.
Wireless Ecosystem
Both meters integrate with mobile apps, but their ecosystems differ:
- Fieldpiece Job Link® provides system-level HVAC data visualization — perfect for balancing systems and sharing reports with clients.
- Fluke Connect® integrates with a range of Fluke instruments, letting electricians view and log multiple readings (voltage, insulation resistance, current) simultaneously.
If your workflow involves many Fluke tools, the Connect ecosystem adds significant value.
Build & Design
Both are rugged and built to withstand daily field use.
The SC680 features a strong magnetic hanger and intuitive interface tailored for HVAC readings.
The Fluke 376 FC, with its slim clamp and flexible iFlex probe, is slightly more ergonomic for electrical panel work.
Power & Temperature
Fieldpiece wins here with dual thermocouples for real-time superheat/subcool data – a must for HVAC pros.
Fluke requires an external temperature probe (sold separately), and lacks built-in power factor measurements.
