Description
With its compact size and easy handling, this lux meter is the ideal measuring device for anyone who wants to take quick light measurements. After removing the lid, the lux meter delivers reliable results in seconds. With a large measuring range of up to 200 klx or 20 kfc, the lux meter offers a wide range of applications in different lighting environments.
With the min-max-hold value display, the lux meter ensures that the most important values are not overlooked, while the temperature display provides additional information about the measuring environment. The lux meter has an easy-to-read LC display. Up to 12 measured values can be stored and called up in the internal memory.
The automatic switch-off function prevents uncontrolled battery discharge. When the lid is open, the lux meter switches off automatically after 15 minutes and when the lid is closed, after one minute of inactivity. With standard AAA batteries, an operating time of up to 60 hours can be achieved.
