The quality of hay and straw is an important factor for nutrient supply and health of animals in the livestock farming. Only the drying of the mown grass makes the forage becomes durable and therefore also storable. If the hay is too moist, for example, bacteria and molds can spread. Forage or bedding material becomes unusable. It is therefore important to check the moisture content of hay and straw. This can be done particularly conveniently and precisely with the hay moisture meter from PCE Instruments. The hay moisture meter was specially developed to determine the moisture and temperature of hay and straw.

The hay moisture is an important indicator to monitor the fermentation process in the hay. If fermentation takes place in the hay, the feed has no nutritional value for the animals. Therefore, a low hay moisture is important. This can be determined quickly and easily with the hay moisture measuring device. Ideally, the value is 13 percent. In principle, the following also applies: the drier the hay and straw are, the less likely it is that bacteria and fungi will spread. However, the hay should not be too dry either, otherwise it will become too brittle and lose its quality. The manufacturer has designed the hay moisture measuring device with a measuring range of 9 to 50 percent.

In addition to the hay moisture, an important parameter in the production of hay is the temperature of the forage. If the temperature is too high, there is a risk of hay and straw self-ignition. The hay moisture meter from PCE Instruments also helps to monitor this important indicator. The measuring range of the hay moisture meter is in this area from 0 to 100 degrees Celsius.
Hay moisture meter are used for monitoring hay. The hay moisture meter determines these important parameters for quality and storage by means of a measuring probe. The stable measuring probe of the hay moisture measuring device is made of robust stainless steel and is available in four different lengths (25 cm, 50 cm, 100 cm, 200 cm). In order to record the moisture and temperature precisely, the user should insert the probe at a 45-degree angle in the hay or straw bales. The illuminated LC display of the hay moisture measuring device shows the determined value immediately. To get a better overview of the conditions inside the bale, the measurement should be repeated at different points on the bale. The probe of the hay moisture meter becomes slightly warm due to the multiple punctures in the bale. In order to obtain the meaningful results, the probe should cool down from time to time. The display lighting of the hay moisture meter switches off automatically after 20 seconds to save the battery power. When no button is pressed, the hay moisture meter switches to the sleep mode even after two minutes.

However, the hay moisture meter can be easily reactivated via the temperature or humidity button. The manufacturer has equipped the hay moisture meter with a practical hold function to freeze the measured value if the result cannot be read-out directly. This is useful, for example, when measuring the moisture of the bales stored on a trailer. The hay moisture meter from PCE Instruments can also be used to get an average value based on several moisture measurements. There is also an option of counting the number of already carried out measurements with the help of the hay moisture meter.


Straw can be checked by hay moisture meter. The user-friendly hay moisture meter is ideal for determining moisture and temperature in the hay and straw bales. The compact and handy shape as well as the battery operation of the hay moisture measuring device guarantees flexible, location-independent use. The hay moisture meter from PCE Instruments is ideal for determining the important indicators for the storage and quality. The hay moisture measuring device is used in agriculture, in the hay and straw trade or in drying plants.
