Fluke-345

Product Description

It combines a true-rms clamp meter with power quality measurement capabilities, including harmonic analysis, power measurements, and data logging. The device features a large backlit LCD display with a graphical waveform view, making it easy to identify power quality issues on-site. With a CAT IV 600V safety rating and a current measurement range up to 3000A AC/DC, the Fluke 345 is suitable for primary distribution panels and heavy industrial loads. The Fluke 345 is equipped with a flexible current probe (iFlex) that allows measurements in tight spaces and around large conductors. It measures voltage, current, power (kW, kVA, kVAR), power factor, and energy (kWh). Harmonic analysis up to the 50th order is available for both voltage and current, with a THD display and waveform capture. The instrument also includes a data logging function that can store up to 50,000 records, which can be transferred to a PC via USB for detailed analysis using Fluke's PowerLog software. Designed for rugged industrial environments, the Fluke 345 meets IP56 protection against dust and water ingress. It operates in temperatures from -10°C to +50°C and can store data in temperatures down to -20°C. The device is powered by a rechargeable Li-ion battery, providing up to 10 hours of continuous operation. With its comprehensive feature set and robust build, the Fluke 345 is an essential tool for maintenance engineers, electricians, and energy auditors who need to diagnose power quality problems and ensure efficient operation of electrical systems. The Fluke 345 Power Quality Clamp Meter is a handheld, battery-powered instrument designed for comprehensive power quality analysis in industrial and commercial electrical systems.

Technical Specifications

Version & Model Difference

The Fluke 345 is part of Fluke's 340 series, which includes the Fluke 343 (basic power logger) and the Fluke 345 (power quality clamp meter). The 345 adds harmonic analysis and waveform display compared to the 343. There is also the Fluke 345-S (with iFlex probe included) and the Fluke 345 (with standard current clamp). The Fluke 345 is often compared to the Fluke 435 series, but the 345 is more compact and portable, while the 435 offers more advanced power quality analysis (e.g., flicker, unbalance, transients). The Fluke 345 has been updated with the Fluke 345-iFlex model, which includes a flexible current probe for easier measurements in tight spaces.
