About

feiffer LMS

Features
Read full description

Accurate and easy loss measurement. This app serves to calculate grain loss during the cutting and threshing. It helps you to avoid big losses, to calibrate the electronic loss control and to set up your combine harvester optimally. To use this app you need the LMS KIT (Loss Measuring System) from feiffer consult. And this is how it works: one to three loss pans can be fixed to the combine with flexible magnetic holders (possible over the entire working width). The test panels are automatically cast by remote control. Threshing losses are detected. A blower facilitates the separation of grain losses. The grains are weighed by means of a pocket scale.The result is input into the feiffer LMS app. An accurate loss value is calculated on the basis of the specific yield and the combine harvester parameters. This app is usable universally for all grain crops and all types of harvest combines. The result is calculated in %, kg/ha and €/ha. This app is free and does not require any in-app purchases.

KRL SmartBox

Features
Read full description

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.
