Accurately displays light level in terms of Foot Candles (Fc) or Lux over wide range. Measures from 0 to 5000 Fc in three ranges with resolution from 0.1 Fc, and 0 to 50,000 Lux in three ranges from 1 Lux. Easy to operate — simply switch to range desired. Accurate to 5% ±2 digits. Precision selenium photovoltaic cells provide for excellent accuracy and sampling time of 0.4 seconds. Automatic zero adjustment. Large 0.5"" digital LCD display also indicates overrange. Powered by 9-volt battery (included). Dimensions: 6.4 x 2.8 x 1.2"".
Monitor light levels using built-in analog output. 1 mV per count output enables you to capture readings on a recorder.

Includes a certificate with an individual serial number indicating instrument traceability to standards provided by NIST (National Institute of Standards and Technology).
