GM640 GRAIN MOISTURE METER

The GM640 moisture meter is a precise and easy-to-use device, specially designed for measuring the moisture and temperature of various types of grains and feeds, such as wheat, rye, oats, barley, corn, rapeseed, soybeans, rice, and animal feed.

Wide measurement range

The device offers moisture measurement in a wide range from 5% to 30%, allowing for precise monitoring of grain quality. Additionally, the moisture meter measures temperature in the range from -10 to 60°C, enabling a comprehensive assessment of the condition of the stored material.

Advanced measurement programs

The GM640 has eight dedicated measurement programs, each assigned to a specific type of grain. The collected data is processed by coded transducers, ensuring the most precise and reliable results that reflect the actual condition of the tested grain.

Precise measuring probe

The device is equipped with a two-pin probe with an advanced LSI converter, which guarantees fast and accurate moisture readings. This makes measurements efficient and reliable, making this moisture meter an indispensable tool in both agricultural and food industry settings.

The GM640 moisture meter is a versatile solution that will perform well in various applications, enabling effective monitoring of the condition of grains and feeds, which translates to better quality and safety of products.

DEVICE FUNCTIONS

• Grain type selection: The device allows for the selection of a specific type of grain, making measurements more precise and tailored to the sample being tested.
• Precise moisture measurement: The GM640 offers accurate moisture measurements of grains, providing reliable information about the water content in the tested sample.
• Temperature measurement: The device measures the temperature of the grain, allowing for a comprehensive assessment of the condition of stored products.
• Moisture standard setting: There is an option to define the acceptable moisture level for a given grain. If the standard is exceeded, the moisture meter will trigger an alarm, notifying of the irregularity.
• Backlit display: The backlighting function ensures readability of results, even in low light conditions.
• Temperature unit selection: The device allows for the selection of temperature measurement units – °C or °F, adapting to user preferences.
• Battery level indicator: The built-in battery charge indicator informs about the need for power replacement, ensuring continuous operation.
• Automatic shut-off: To save energy, the moisture meter automatically turns off after a period of inactivity.
• Measurement hold function "HOLD": The ability to freeze the reading on the display allows for accurate recording of the measurement result.

CHOOSING THE RIGHT GRAIN TYPE

When using the moisture meter, it is important to correctly select the appropriate grain type to obtain the most accurate measurement results. Below is a list of available types of grains:

• BROWN RICE: An ideal choice for rice that has not undergone the husking process.

• WHEAT: A dedicated mode for measuring moisture content in wheat, a commonly used grain.

• BARLEY: An option for precise moisture measurement of this grain, often used in feed production and the brewing industry.

• FEED: Designed for measuring moisture in feed mixtures to ensure optimal storage conditions.

• CORN: An excellent mode for testing the moisture of corn grains, both in raw and processed forms.

• RAPESEED: Choosing this mode allows for precise determination of moisture content in rapeseed grains.

• SOYBEANS: Designed for measuring moisture in soybean grains, which are an important ingredient in many food and feed products.

• WHITE RICE: A measurement mode ideal for rice that has been stripped of its outer husk, ready for consumption or further processing.

If the measured grain type is not on the above list, it is recommended to select the closest type, considering the size and dimensions of the grain. This will allow for obtaining the most precise and reliable measurement results.
