The Digital Illuminance Meter is a precision instrument used to measure illuminance in the field. It is fully cosine corrected for the angular incidence of light. The illuminance meter is compact, tough and easy to handle owing to its construction. The light sensitive component used in the meter is a very stable, long life silicon diode. SPECIFICATIONS: DISPLAY: 3-1/2 digit LCD. Measuring Range: 200, 2,000, 20,000 and 200,000Lux (20,000Lux range reading×10, 200,000Lux range reading×100) 20, 200, 2,000, 20,000FC (20,000FC range reading×10) *1FC+10.76Lux Over range display: Highest digit of "1" is displayed. Accuracy: ±(3%rdg +10dgt) ≤20,000Lux/2,000FC ±(5%rdg+10dgt) >20,000Lux/2,000FC (Calibrated to standard incandescent lamp at color temperature 2856K) Repeatability: ±2% Temperature Characteristic: ±0.1%/℃.
