LIGHT METER [Lux]: Digital
This digital illuminance meter measures light levels ranging from 0.1 Lux to 200,000 Lux . Records from zero to sunshine light levels making it very handy for the Biology Department.
FEATURES: Accurate and instant fast reading response time. Spectral sensitivity close to CIE photopic curve. Spectral correction actor function SCF (include LED). Cosine angular corrected. Has lead reading data hold function. Relative value comparison function. Maximum/Minimum recording function. User calibration function (CAL). Analogue output function.
Display: 3½ digit LCD display. (Overall Display Range: Highest digit of  is displayed.)
Measuring Range: 200 / 2000 / 20000 / 200000 Lux (1 Footcandle = 10.76 Lux) (1Lux = 0.0929 Footcandle)
Resolution: 0.1 Lux.
Accuracy: +-3% rdg+-10dgts (<10,000 Lux), +-4% rdg+-10dgts (>10,000 Lux), calibrated to standard incandescent lamp, 2856DegK.
Temperature Characteristics: +- 0.1% / DegC
Measuring Rate: approximately 2.0 time/sec
Photosensor: Silicon photodiodes.
Operating Temperature + Humidity: 0 DegC ~ 40 DegC (0% ~ 70% RH)
Storage Temperature + Humidity: -10 DegC to 60 DegC (0% to 70% RH)
Power Source: 1x 9-Volt Battery
Battery Life (typical): 500 hours (carbon zinc)
Photosensor: Lead length 150cm approx. (Photosensor Dimensions: 105 x 60 x 30mm LxWxH)
Dimensions: 135 x 72 x 33mm (LxWxH)
Accessories supplied: Instruction manual, Carrying case, 9V Battery
NOTE: The 200,000 Lux range is not found in all Lux meters. Some being offered to schools only measure up to 50,000 Lux – cannot be used to measure outside light levels.
