The LECO TGM800 delivers a high-precision, fully automated solution for moisture determination by replacing traditional, time-consuming loss-on-drying methods with a modern thermogravimetric approach. Designed to improve laboratory efficiency and consistency, the TGM800 combines multi-sample automation, intelligent endpoint detection, and intuitive Cornerstone® touch-screen software.
Capable of analyzing up to 16 samples simultaneously, the TGM800 significantly reduces hands-on time while ensuring accurate and reproducible moisture results. Its versatility makes it suitable for a wide range of applications, including food, feed, milled products, and agricultural materials.
LECO TGM800
The TGM800 is suitable for moisture determination across a broad range of sample types, including:
The TGM800 is a thermogravimetric analyzer designed to directly measure moisture content using a controlled loss-on-drying technique. Moisture is determined by continuously measuring sample mass as a function of oven temperature while precisely controlling atmosphere and ventilation conditions.
The instrument integrates a computer, a four-place analytical balance, and a multi-sample oven that enables the simultaneous analysis of up to 16 samples. Once an analysis method is selected, empty aluminum foil crucibles are loaded into the oven carousel. The system automatically tares each crucible before sequentially presenting them to the operator for sample loading. Initial sample masses are measured and stored automatically.
After sample loading is complete, the analysis begins with controlled oven temperature ramping and the initiation of ventilation. Each crucible is automatically indexed and lowered onto the balance pedestal, where the sample mass is recorded. This process continues sequentially for all samples throughout the analysis.
Mass loss is continuously monitored for each sample while the oven temperature and ventilation rate are regulated according to the selected method. Analysis duration can be defined either by a fixed time or by achieving sample mass constancy. Moisture content is calculated as percent mass loss and reported individually for each sample at the conclusion of the run.
The intuitive touch-screen interface provides full access to method creation, analysis control, diagnostics, and reporting in a highly organized environment. Methods can be customized with user-defined oven temperatures, ramp rates, atmospheres, and ventilation settings. Real-time plots of sample mass loss and temperature are displayed on screen, while all results and calculations are automatically stored and managed by the software.
By enabling batch processing of up to 16 samples with automated mass measurements, the TGM800 maximizes laboratory productivity, analytical consistency, and overall workflow efficiency.
