Supplied with full traceability and documentation. Request... Price & Availability 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. Basic Product Information Power quality analysis: harmonics up to 50th order, THD, power factor True-rms voltage and current measurements for accurate readings on distorted waveforms Data logging with 50,000 records and USB PC interface CAT IV 600V safety rating for primary distribution use IP56 rated for dust and water resistance Measures AC/DC current up to 3000A with flexible iFlex probe 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. Application Scenarios Does the Fluke 345 measure harmonics? Yes, the Fluke 345 performs harmonic analysis up to the 50th harmonic for both voltage and current. It displays THD (total harmonic distortion) and can show harmonic spectra on the graphical display. Is the Fluke 345 suitable for three-phase measurements? The Fluke 345 is primarily designed for single-phase measurements, but it can be used on three-phase systems by measuring each phase individually. For simultaneous three-phase power quality analysis, Fluke recommends the Fluke 430 series, which offers three-phase measurement capabilities. What is the battery life and how is it charged? The Fluke 345 uses a rechargeable Li-ion battery that provides up to 10 hours of continuous operation. It is charged via an AC adapter (included) or through the USB port when connected to a PC. The battery can be replaced by the user. What is the maximum current the Fluke 345 can measure? The Fluke 345 can measure AC/DC current up to 3000A when using the optional iFlex flexible current probe. With the standard clamp (if included), the range is typically up to 2000A AC. The iFlex probe allows measurement around large conductors and in tight spaces.
