DESCRIPTION
Illuminometer
Handheld lux meter with automatic range selection, displays measuring units in lux or footcandle

PCE-LED 20 is a Illuminometer with an external LED light sensor. The cable of the sensor has an extended length of approx. 1.5 m / 4.9 ft. Different work or production processes require different lighting conditions. In school, office and factory environments, lighting must also meet applicable safety standards. Indoor lighting conditions can be assessed quickly and easily using this meter. The Illuminometer or lux meter can display measured values directly on the display. A direct measurement is thus immediately possible. By means of various presets, the functions installed in the device can also be activated or deactivated. These functions include the normal HOLD function, in which the measured value is frozen in the display. In addition, the extreme values as well as the average value can be frozen in the display. Further functions of the LED lux meter are the zero adjustment, the automatic shutdown and the automatic range selection.

Measurements are possible with the Illuminometer in lux or footcandle. The unit has only seven keys, allowing for one-hand operation. This also makes the instrument simple to use. The Illuminometer is a battery-powered handset, making the device portable and ideal for measurements in the field.

The measuring sensor of the Illuminometer has a large exposure area. For convenience, the sensor is located on a coiled cable that can be extended to full length only when needed. A protective cap on the sensor prolongs its life. This protective cap should be placed on the sensor during storage. In addition, the protective cap is required when a zero adjustment is to be performed on the Illuminometer.
