Fits basic Fc/Lux measurement with recorder output where you need an Extech 401025 covering up to 5000 Fc / 50,000 Lux with ±5% full scale accuracy and 1 mV per count analog output.
Key advantages
- Fc ranges — 0–200 / 0–2000 / 0–5000 Fc
- Lux ranges — 0–2000 / 0–20,000 / 0–50,000 Lux
- Accuracy / resolution — ±5% full scale; 0.1 Fc or 1 Lux
- Response — Fast 0.2 s or slow 0.4 s selectable
- Analog out — 1 mV per count for recorder capture; cosine/color corrected sensor
Typical applications
- Basic lighting surveys.
- Recorder capture via analog output.
- Fc/Lux switching in the field.
Selection guide
- Fc vs Lux range
- Fast/slow response
- Analog output — Recorder needs
- Cable — 45 in sensor cable included
Common mistakes
- Expecting datalogging like HD450.
- Ignoring ±5% FS class vs ±3% meters.
- Leaving sensor uncovered in storage.
