Schaller Humimeter RHL Grain Moisture Meter

humimeter RHL moisture meter for grain stores and silos

The humimeter RHL measures the moisture content, temperature, relative humidity and dew point of grain up to a depth of 2m. Up to 10,000 measurement values can be stored either manually or automatically on a time based interval.

An optional aw-value chamber is available for small sample volumes

Measuring procedure and data handling:

The main unit of the humimeter RHL enables the connection of different humidity sensors. With the aw-value measuring chamber it is possible to measure small sample volumes. Upon powering the device, temperature and humidity values will be displayed. The measurements can be stored manually by pressing a button or automatically using a timed interval on the data logger. The measuring device provides curves for wheat, barley, rye and triticale. Further grain varieties can be added on request. With the help of a capacitive humidity sensor you can determine the balance humidity. The addition of the optional USB data interface module enables connection of the RHL device to a PC and both storage and evaluation of the measured data through Log memorizer software.
