SDTGA400 can be used to determine the moisture content on air dried basis and total moisture in coal,
coke, petroleum, minerals and so on. It can be vastly used in power industry,coal,fuel & chemical processing,metallurgical industry,environmental protection, papermaking, geological industry, and
researching institute, etc.

With the provision for passing a stream of dry nitrogen and a high-precision flow meter, SDTGA400 meets
requirements of umpire analysis.
Easy Operation and Multi Control
Automatic weighing function could display real-time sample weight and calculate test results automatically.
A single computer can control several sets of SDTGA400.
Powerful Data Management
SDTGA400 has powerful data management, report statistics and printing function. Balance and network are
connected by standard interface RS232.
