401025 is a Foot Candle/Lux Meter which measures light level to 5000FC (foot-candles) and 50,000 Lux with a 5% accuracy using a precision photo diode and color correction filter. Meter features fast/slow response time and an analog output (1mV per count) for capturing readings to a recorder.
- Accurately displays light level in terms of Fc or Lux over three ranges:
- Fc (0-200, 0-2000 and 0-5000Fc)
- Lux (0-2000, 0-20000, 0-50000Lux)
- Resolution of 0.1Fc or 1Lux with 5% accuracy
- Select fast (0.2 second) or slow (0.4 seconds) response
- Monitor light levels using outputs; 1mV per count analog output for capturing readings to a recorder
- Utilizes precision photo diode and color correction filter; Cosine/color corrected
- Complete with 9V battery and light sensor with 45" (1.1m) cable and protective cover
- Extech 401025-NIST available. Call for pricing.
