The Labmart MD-7822 Grain Moisture Meter is a portable digital instrument designed to measure moisture and temperature in grain samples. It features a probe-based measurement system, backlit LCD display, data hold, grain-species selection, maximum-value measurement, low-battery indication and automatic temperature compensation. It is suitable for agricultural inspection, grain procurement, storage and processing applications.

Product Overview

The MD-7822 is a compact digital grain moisture and temperature meter intended for rapid inspection of agricultural grains. A measuring probe is inserted into the sample, allowing the instrument to display moisture and temperature readings.

The meter is designed for practical grain-quality assessment and can be used during grain allocation, purchasing, storage and processing. Its backlit display, data-hold function and grain-species selection make it convenient for routine field and laboratory measurements.

The available technical information specifies an overall moisture measurement range of 2–30%, while product descriptions for the grain-specific application also identify common grain testing in the 8–20% range. For purchasing and application decisions, the applicable grain-specific range should be confirmed for the selected grain type.

Key Features and Benefits

• Moisture & Temperature Measurement: Measures both moisture content and temperature of grain samples.
• Probe-Based Testing: Insert the probe into the grain sample for measurement.
• 2–30% Overall Moisture Range: Provides a broad stated measurement range for moisture testing.
• Automatic Temperature Compensation: Helps account for temperature effects during measurement.
• Grain Species Selection: Allows selection of the appropriate grain type for testing.
• Backlit LCD Display: Makes readings easier to view in different lighting conditions.
• Data Hold Function: Holds the displayed measurement for convenient recording.
• Maximum Value Measurement: Provides a maximum-value measurement function.
• Low-Battery Indication: Alerts the user when battery power is low.
• Portable Design: Compact handheld construction is convenient for grain inspection at different locations.

4. Technical Specifications

Specification note: Available product information contains differing descriptions of the moisture range. The technical specification states 2–30%, while the grain-specific description states 8–20% for paddy, rice, corn and wheat. These figures should not be treated as interchangeable; the applicable range depends on the selected grain/application.
