HT Instruments F3000 Digital Clamp Meter AC/DC TRMS 600A 1000V CAT III / 600V CAT IV

The HT Instruments F3000 stands out with its True RMS AC/DC current measurement up to 600 A and a 40 mm jaw opening, making it suitable for conductors in tight distribution panels. Unlike basic clamp meters, it also measures temperature with a K-type probe and includes inrush current capture for motor start-up analysis.

Highlights

• True RMS AC/DC current up to 600 A with 40 mm jaw opening
• AC/DC voltage up to 1000 V with CAT III 1000 V / CAT IV 600 V safety rating
• Measures resistance, frequency, capacitance, temperature, continuity, and diode
• Non-contact voltage detection and inrush current measurement
• Backlit 3000-count display with data hold and auto-ranging

In daily use

The F3000 is built for electricians and maintenance technicians who need reliable readings in demanding environments. The True RMS function ensures accurate measurements even with distorted waveforms, while the backlit display and data hold make it easy to work in low-light or awkward positions. The non-contact voltage detector adds an extra layer of safety before you start testing.
