HF-PQ-T202 Waveform Recorder
Power Quality Analyzers: Handheld, Portable or Twelve-Channel Recorder?
Four instruments for measuring power quality, split by how the measurements get used: a meter for field surveys, a handheld analyzer with harmonic coverage, a clamp-on unit built for long unbalance studies, and a multi-channel recorder for waveform-level investigation.
Quick comparison
| Model | Form factor | What separates it |
|---|---|---|
| HF-PQ-204 portable power quality meter | Portable | Frequency 45–55 Hz centred on 50 Hz with error ≤0.02 Hz; voltage input 20–900 V; accuracy ≤0.5 % F.S. |
| HF-PQ-205 handheld analyzer | Handheld | 0–800 V with automatic range switching, 45–65 Hz, harmonics to the 63rd, current 5 A / 25 A standard with 100 A–2000 A clamps optional. |
| HF-PQ-T201 unbalance analyzer | Clamp-on, fixed | Built for 24/7 three-phase current tracking: 0–200 A clamp standard, 500 A / 1000 A optional, Class 1.0, storage up to 3 years, 2 kg. |
| HF-PQ-T202 waveform recorder | 12-channel bench unit | Harmonics to the 1024th, 12 low-voltage/current channels, ±400 V and ±20 mA inputs, 12.1-inch touchscreen, 8 GB internal storage. |
Before you specify one
- Decide whether you need statistics or waveforms. A meter gives you averages, maxima and event counts. A waveform recorder gives you the shape. If the question is "how bad does it get", a meter answers it; if the question is "what actually happened at that instant", you need the recorder.
- Check the harmonic order you actually need. The handheld reaches the 63rd harmonic, which covers the usual distribution-network questions. Switching and converter investigations can run far higher, and that is where the 1024th-order coverage of HF-PQ-T202 matters.
- Match the clamp to the feeder. HF-PQ-T201 ships with a 0–200 A clamp; 500 A and 1000 A are optional. Ordering the clamp after the instrument arrives is the usual cause of a second shipment.
- Check the recording window against the study length. HF-PQ-205 stores up to 18 months at a 1-minute interval and HF-PQ-T201 up to 3 years — both are long enough that a multi-week study will not run out of memory mid-way.
Analyzer or monitor?
An analyzer is carried to site for a survey and is the right starting point when the problem is not yet characterised. Once you know which feeder and which parameter matter, a permanently installed power quality monitor records the same parameter continuously and catches the event that happens while nobody is on site.
Common questions
Which one suits a one-day site survey?
HF-PQ-204 or HF-PQ-205. Both are portable, both cover voltage, current, frequency and harmonics, and neither needs a panel modification to install.
Which one tracks unbalance over months?
HF-PQ-T201. It is built specifically for continuous three-phase current tracking, with 3-year storage and a clamp that opens around an existing cable.
How long does delivery take?
Standard models ship in 7–15 working days; configured or custom variants take 25–35 days.
Datasheets for each model are on the product pages and in the datasheets library. Measurement methods described in our application guides reference the IEC and IEEE standards that apply to the quantity being measured.
