82. tion of Features and Principles of Operation 2 1 Principles of Operation This unit determines the moisture and solid contents of samples by heating them using infrared illumination and measuring changes in mass due to evaporation This is referred to as the drying loss method and is the simplest method for determining moisture content and thus mandated by many public regulations related to measurement standards 2 2 Features UniBloc sensor The core mechanism of the internal precision balance is the UniBloc cell which provides excellent responsiveness temperature characteristics and shock resistance This UniBloc sensor ensures excellent reliability in moisture content measurements over a long period of use New Auto Taring Function The MOC 1 20H comes with an internal Auto Taring Function which makes it possible to perform reset correction while performing measurements thus eliminating drift of the balance even when performing measurements over a long time and making it possible to obtain extremely reliable measurements Mid infrared quartz heating lamp The MOC 120H uses a mid nfrared quartz heating lamp with a central wavelength of 2 6 um This heater provides excellent drying efficiency over a wide range of different types of sample minimizes the differences in heating due to the different colors of samples and eliminates the overheating of sample surfaces thus making it possible to obtain ideal d
