Description R.T.S. Inc. mi 76-3010 R-77 Footcandle Meter (Grey)
A Pocket sized color and cosine corrected three scale meter that directly reads illuminance from 10 to 1000 foot-candles (fc) and up to 10,000 fc with the use of the included 10x multiplier. The Diffusing plate on top of the meter case is designed to collect light from wide angles so that the cell response will be a function of the cosine of the angle that the incident light makes with the perpendicular Light reaching the meter from various directions is therefore measured accurately. A special filter mounted over the meter cell matches the color sensitivity of the meter closely to that of the human eye. No correction factors are necessary for measurements involving light sources with different spectral characteristics. Simply read the meter directly.
