Fluke’s T6 series electrical testers are known for their FieldSense™ technology, which allows electricians to measure voltage and current without making direct contact with live conductors.
Within this series, the T6-600 and T6-1000 are two of the most popular models. While they share many similarities, the main differences come down to voltage range, measurement capacity, and application environment.
📋 Overview of the Fluke T6-600
The Fluke T6-600 is designed as a compact, everyday tester for electricians and technicians who work with standard residential and commercial systems.
Key Features:
- FieldSense™ technology: measure voltage (up to 600V) and current through the open jaw without contacting live conductors
- Measures voltage up to 600V AC/DC
- Measures current up to 200A
- Frequency measurement up to 1 kHz
- Continuity and resistance functions
- Simultaneous voltage and current display
- Safety rating: CAT III 600V / CAT IV 300V
The T6-600 is an affordable, portable, and safe option for general electrical troubleshooting in most residential and light commercial applications.
📋 Overview of the Fluke T6-1000
The Fluke T6-1000 is the premium version of the T6 series, designed for technicians who work with higher-voltage systems, such as industrial and commercial environments.
Key Features:
- All the features of the T6-600
- Measures voltage up to 1000V AC/DC
- Measures current up to 200A
- Wider open jaw for larger conductors
- Higher safety rating: CAT III 1000V / CAT IV 600V
- Frequency measurement up to 1 kHz
- True-RMS for accurate measurements on non-linear loads
The T6-1000 is the right choice for professionals who need higher voltage capacity and broader safety ratings.
