FAQ

How to do a measurement with the moisture meter AGRETO GFM?

Unscrew lid, fill the measuring chamber of the appliance to the brim, remove excess material and screw the cover back on the device. Pull the cover where known until the spring-loaded indicator is at the height of the lid. Now you can start the measurement and a few seconds later read the result. The crop used last is saved. If you have previously measured a different crop, you must select the right crop before the measurement.

Which crops can be measured?

The AGRETO GFM has calibration curves for a total of 41 crops. A detailed list can be found in the technical data.

What is the measuring accuracy of the moisture meter GFM?

In common with all similar field devices, the AGRETO GFM determines an electrical value which is converted with the aid of a calibration curve to the moisture level. It fits the calibration curve to the crop and the characteristics of the sample (maturity, bulk density, variety …)  The measurement results are largely consistent with calibrated equipment or reference measurements in a drying cabinet. Due to the different properties, in practice variations in the result occur.  The differences in practical use are usually no larger than. + / – 0.5 percentage points.

Can or must the calibration curves be re-calibrated?

Yes, every single crop can and should be recalibrated from time to time.  At the beginning of the harvest season, it is recommended to compare the required calibration curves with the device of your dealer and readjust if necessary

Why should always be several measurements carried out?

In comparison to other units, the Agreto moisture meter GFM has a relatively large sample size. The risk of the sample not being representative is thus smaller, but still present. An average of several samples and measurements is thus meaningful. When using a moisture analyzer at the field during harvesting, the samples from different locations in the field have to be taken into account.

Can the GFM measure moisture in crops for which no calibration curve is included?

The calibration curves cannot be extended or renamed.  However, you can adjust the calibration with a sample and a reference device. If you want to measure, for example, pumpkin seeds, then you could use any calibration for sunflowers. Measure a pumpkin seed sample with the reference instrument and the same sample with the setting for sun flowers with the GFM. Adjust the calibration curve for sunflowers on the GFM so that it fits together with the reference device. Now you can measure your pumpkin seeds with the calibration for sunflower.

What is used for the power supply of the device?

The GFM has two battery compartments for a 9 V block. One of them is used for the measurement electronics, the second for the backlight.

How long do the batteries last?

This depends on the frequency of use. Generally the device can be operated for several years with a battery. By using a second battery for the lighting (which is rarely needed), there is virtually always a spare battery available.
