Page 18: Measurement
RHL grain moisture meter with data log user manual Measurement Preparing a measurement To do so: The device has to have nearly the same temperature as the product being measured. It is recommended to let your humimeter device adjust to the surrounding temperature for at least 30 minutes before the measurement.
Page 19 ATTENTION Injury hazard Risk of injury by the measuring head ► Keep the measuring electrodes away from your body during all activities. ► Keep the measuring electrodes away from other people' bodies during all activities. Information - Measuring accuracy This rapid and non-destructive measuring procedure allows you to quickly take moisture readings at a number of different points.
Page 20: Adjustment Behaviour Of The Sensor
RHL grain moisture meter with data log user manual Adjustment behaviour of the sensor In humidity and temperature measurement, several parameters are responsible for the adjustment behaviour (time until the actual measured value is displayed). The para- meter that can cause the highest measurement error is the temperature difference between the sensors, as well as the entire measuring device, and the material to be measured, or the air.
Page 21: Memory Function
Memory function Hold function - Freezing the displayed values The device can be configured in such a way that the information being shown on the display will freeze at the touch of a button until a new button is pressed. This function can be used if the measured value should remain on the display.

Page 31: Definition Water Activity
The aw-value is temperature dependent, for an aw-value determination at the desired temperature the instrument and the sample should be pre-stored at this temperature. The humimeter RHL Aw-value measuring device is suitable for measuring materials such as grain products, coffee, cocoa, cereals, butter, dried fruit mixtures, spices, gra- nulates, mushrooms, sugar, xylitol, cookies or even dried sausage as well as many other food products for which a testing of the aw-value is necessary.
Page 32 RHL grain moisture meter with data log user manual The water activity should not be mistaken for the water content - the percentage of water in a product! The water content is used to calculate the dry content of food and materials, it indicates the ratio of water to the total mass as a percentage (kg/kg) x 100.
Page 33: Application Range
Typical sorption isotherms of various foods and materials from the literature: Application range The device functions in the normal application range (normal range) within the specified accuracy. Long-term use outside the normal application range (max. range), especially at humidity above 80 %, can lead to higher measurement deviations (+3 % after 60 h).
