PCE-L 100 is a high-accuracy lux meter that measures the intensity of both natural and artificial light rays. The PCE-L 100 lux meter or light meter also functions as a luminance meter (with optional accessory) to measure overlay and remote light density.

The PCE-L 100 lux meter or light meter comes with a graphic display that allows you to view different measurement values at the same time. With the light meter display, you will see measurement values, current measurements 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 light meter to make the measurement analysis easier. The light meter offers 5 measurement types: single measurement, single measurement in %, continuous measurement, continuous measurement in %, and integrating measurement (measurement of the field of view illumination).

The PCE-L 100 light 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) to note, for example, the place and person who performed the measurement. Data can be recorded both manually or automatically by selecting a measurement quota. The PCE-L 100 light meter will display the time of the record depending on the measurement quota. Recorded data have the following information: date and time, comment, measurement value, measurement unit, statistics, max, min, and average values as well as the relation between min, max, and average value. Data can be analyzed and edited via the software that is included in the delivery. The PCE-L 100 light meter can operate as a luminance meter (with optional accessory) to calculate remote measurements with a measurement angle of 1º, 3º or 10º of the luminous source. 

Thanks to its high accuracy, its price and its durability, the PCE-L 100 light meter is used in many professional sectors where a precise light wave measuring instrument is required.

Dimensions: Ø 44 x 25.5 mm / 1.7 x 1 in
1.5 m / 4.9 ft cable (plug connection)
Luminaire attachment (optional, included in the PCE-L 100LV set) 
For luminance measurement from a greater distance, there is a distance-luminance attachment for the light intensity meter, which with a 1 ° measuring angle in the range from 1 m / 3.3 ft up to infinitely accurate measured values ​​can deliver. This can be easily attached to the tripod and simplifies the sighting of the measuring surface. The lens is 100 mm / 3.9 in, f / 2.5. Target device is Kimme - Korn. The measurements can be controlled by the light intensity meter or the distance-luminance intent by pressing a button. The dimensions of the luminance attachment are 126 x 169 x 44 mm / 5 x 6.7 x 1.7 in. Weight approx. 550 g / 1.2 lbs. Measuring surface Ø / m see instructions Light intensity meter PCE-L 100.
