Extech 401025 Foot Candle/ Lux Meter 5,000 Fc / 50,000 Lux

The Extech 401025 accurately displays light level in terms of Fc or Lux over three ranges. The 401025 also includes analog output for capturing readings to a recorder.

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. Comes complete with 9-Volt battery.

• Accurately displays light level in terms of Fc or Lux over three ranges: Fc (0-200, 0-2000 and 0-5000Fc) and Lux (0-2000, 0-20000, 0-50000Lux)
• Resolution of 0.1Fc or 1Lux with 5% accuracy
• Select fast (1 second) or slow (2 seconds) response time
