PCE-L100 Lux meter

PCE- L 100 Lux Meter for luminous density and intensity
lux meter for light intensity with internal memory / Class A to meet CIE / graphic display / statistical analysis / with many accessories

The PCE-L 100 Lux Meter for light density and intensity is a device to measure light waves. The PCE-L 100 Lux Meter measures light intensity and both natural and artificial rays accurately as well as overlay and remote light density. The high quality PCE- L 100 Lux Meter meets the requirements of the International Commission on Illumination (CIE) as well as precision Class A requirements. The PCE-L 100 Lux Meter comes with a graphic display which can display different measurement values at the same time. On the PCE-L 100 lux meter display, you will see measurement values, current measurement and statistics formed by max., min. and average values as well as the relation between max./min. and average values. It is possible to display the percentage by introducing a reference value in the PCE-L 100 Lux Meter to make the measurement analysis easier. The PCE-L 100 Lux Meter offers 5 measurement types: single measurement, single measurement in %, continuous measurement, continuous measurement in % and integrating measurement (measurement of the field of illumination). The PCE-L 100 Lux Meter has a wide measurement range from 0.001 up to 300 klx divided in three different measurement ranges and can be changed from manual to automatic mode. Measurement values can be stored in the internal memory (512 values) including comments (16 characters), for example, place and person who performed the measurement. There is also an external memory for 511 values via the USB port. Data can be recorded both manually or automatically by selecting a measurement quota. The PCE-L 100 Lux Meter will display the time of the record depending on the measurement quota. Recorded data have the following information: date and time, comment (place and person who performed the measurement), measurement value, measurement unit, statistics, max., min., and average values as well as the relation between min., max., and average value. Data can be analysed and edited via the software that is included in the delivery. The PCE-L 100 Lux Meter can be adapted to some additional accessories indicated below. The PCE-L 100 Lux Meter can operate as a luminance meter for measurements with a measurement angle of 1º, 3º and 10º of the luminous source. Thanks to its high accuracy, its price and durability, the PCE-L 100 Lux Meter is used in many professional sectors where a precise instrument is required.

Additional components

Accurate lux meter for luminous density and intensity PCE L 100 density adapter

Light density adapter:
The PCE-L 100 Lux Meter can be turned into a luminance meter with the luminous density adapter, that means light intensity on the surface (cd/m2). Dimensions: Ø50 x 43 mm.

D = 12.5 mm
2α= 68°
2δ= 107

Light density adapter:
There is an adapter with a measurement range of 1º for remote measurements of light density from 1 m up to infinity. This adapter can be mounted on a tripod. The lens is 100 mm f/2.5. Measurements can be monitored from the lux meter itself or from the luminous density adapter. Dimensions of the luminous density adapter: 126 x 169 x 44 mm, weight: aprox. 550 g. Measurement surfaces are found in the PCE-L 100 Lux Meter user manual.
