## What is KRL SmartBox?

The KRL Smartbox app can be used to retrieve measurement results from the KRL Smartbox via Bluetooth.
The measurement results can be supplemented with further information and then exported as a PDF.

Using the KRL SmartBox makes it possible to measure the corresponding relative humidity of mineral screeds. Changes in the temperature of the sample can influence the measurement of the humidity above it. During measurements with the KRL method at a temperature of 20°C ±5 °C, the expected maximum humidity deviation is ±2% relative humidity.
