The Fluke 43B is the engineer’s choice for diagnosing and troubleshooting power quality and general equipment failures throughout industry.
Circuit breakers that trip, transformers that overheat, motors that burn out, machines that don’t function properly; whatever the problem, you can quickly and easily identify the cause with the Fluke 43B Power Quality Analyzer.
As a Power Quality Analyzer it is optimized for industrial measurements on the 50 Hz fundamental frequency. Because its frequency range extends from 10 to 400 Hz, it’s also ideal for aviation, marine and railway applications.
Besides the unique extended frequency range, the Fluke 43B is the only instrument that combines the capabilities of a Power Quality Analyzer, a 20 MHz oscilloscope, a multimeter and data recorder in a single tool.
1. Power Quality Analyzer
- Measures power (W, VA, VAR) and power factor (PF, DPF)
- Calculates power and power factor on balanced 3-phase loads
- Voltage, current and power harmonics up to the 51st.
- Measures sags and swells on a cycle-by-cycle basis for up to 24 hours
- Automatically captures up to 40 transients as fast as 40 ns
- Measures motor inrush and analyzes using cursors
- Covers broad frequency range (10 to 400 Hz)
|
2. Oscilloscope
- Dual-channel scope
- Up to 20 MHz bandwidth with FREE VPS40 Voltage Probe (Fluke 43B only)
