High-Capacity Thermogravimetric Moisture Analysis

High Precision, High Capacity

The LECO TGM800 delivers precise moisture analysis for foods, feeds, and agricultural products using an advanced thermogravimetric approach. With a high-capacity design, automated weighing, and programmable drying cycles, it eliminates the variability and labor of traditional oven methods, providing fast, consistent results with minimal user interaction.

Built for efficiency, the TGM800 supports batch processing with up to 16 sample positions and robust construction for long-term reliability. No matter the application, the TGM800 helps laboratories reduce turnaround time, improve accuracy, and optimize operator time—all while ensuring dependable performance across diverse sample types.

How the TGM800 Works

The TGM800 uses thermogravimetric loss-on-drying (LOD) to measure moisture content with precision. Up to 16 samples are loaded into automatically-tared aluminum crucibles positioned in the multi-sample oven. Once the selected method begins, the oven heats each sample according to programmed temperature ramps, atmosphere, and ventilation rates.

During drying, each crucible is automatically moved to the integrated balance for sequential mass measurements. As moisture leaves the sample, the TGM800 tracks mass loss until a fixed endpoint or mass constancy is reached. Moisture content is then calculated as percent mass loss for every sample.

A built-in touchscreen provides full method control—temperature, ramp rates, atmosphere, ventilation—and displays live drying curves for temperature and mass. With batch capacity and automated weighing, the TGM800 delivers fast, consistent, and highly accurate thermogravimetric moisture results with minimal operator effort.
