TGM800 Thermogravimetric Moisture


LECO's thermogravimetric moisture determinator, the TGM800, provides a high precision, automated solution, which utilizes a direct method for replacing the slow labor intensive, traditional loss-on-drying analytical techniques. The TGM800 offers a number of time-saving features such as the ability to automatically measure up to 16 samples at a time with optional drying time end point recognition, and intuitive touch-screen software with flexible method settings. The TGM800 is applicable to a wide variety of sample matrices including food, feeds, milled products, and agricultural materials, making it a versatile solution for many laboratories.

Cornerstone Mobile remote software keeps the user updated from their smartphone on the instrument’s analysis batch progress, performance, and status while away.



High throughput and minimal operator time providing maximum productivity and optimal work flow

  • Automated loss-on-drying moisture analysis of up to 16 samples
  • Maximized throughput with rapid ramping of the oven temperature to the method set point and fast cooling post analysis
  • Optimized drying time with automatic end point recognition based upon sample mass constancy
  • Limited sample interaction requirements reduce operator handling time
