GMM 7002L Grain Moisture Meter – High Precision Digital Grain Tester with Temperature Display & Multi-Grain Support

The GMM 7002L is not just a basic moisture checker—it’s a multi-function grain diagnostic tool designed with intelligent features to optimize grain handling at every stage, from harvest to storage. Its internal grain temperature monitoring complements the moisture analysis, helping you make informed decisions about drying, packaging, and storage requirements.

With support for eight commonly cultivated grains—including Paddy, Wheat, Barley, Fodder, Corn, Rapeseed, Soybean, and Rice—the device can be tailored to different harvests or regions. Simply select the grain code using the “SELECT” key and insert the probe into the grain bulk to get instant moisture readings. Results are shown in both °C/°F and %, ensuring clarity and compliance with industry standards.

The programmable moisture standard feature allows you to define critical limits, such as 16.5% for wheat. When this threshold is exceeded, the meter gives an audible buzzer alarm to alert you—eliminating guesswork and reducing the risk of grain spoilage due to excess moisture.

For quality assurance or documentation, the HOLD function lets you retain readings on screen, allowing you to log or photograph values as needed. The Celsius/Fahrenheit switchable mode, combined with an auto power-off feature, ensures user comfort and energy efficiency. Designed with a rugged ABS housing and a detachable stainless-steel probe, the meter is built to withstand daily use in dusty, humid, or remote environments.
