2. Measuring Principle and Features
■ Measuring principle
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 loss on drying method and is
the simplest method for determining moisture content and thus mandated by many public regulations related to
measurement standards.
■ Features
● Auto Taring mechanism
The auto taring mechanism is incorporated in this instrument. This mechanism allows for measurement while
performing a zero point calibration, and therefore, scale drift is eliminated even when a test is performed over a
long period of time. This feature allows for reliable measurement.
● Organic carbon heater
An organic carbon heater is introduced for the heat source. This heater emits infrared rays more than 2 times
stronger than a halogen heater in the wavelength range (2.5 to 3μm) in which moisture reacts with heat. This
feature provides extremely efcient drying.
The service life is 7,000 hours* which is approximately 4 times the life of a comparable conventional infrared
lamp. In addition, it is better for the environment as polluting halides and metals are not used.
* Indicates actual measured time for the operation of infrared heater. This is not a guarantee of service life.
● 2 types of measuring modes
This product provides 2 types of measuring modes, and therefore, can perform measurement under appropriate
drying settings in accordance with the drying characteristics of the sample to be measured. (Automatic mode,
Timed mode)
● Pre Heat mode
This product is equipped with a Pre Heat mode to eliminate a measurement error occurring immediately after
turning on the power or when the temperature inside the measuring instrument is not stable.
● The ability to store measuring settings
Five (5) measuring settings storage numbers are provided. Storing various sample measuring settings on
numbers allows users to perform measuring preparation smoothly.
● Data memory function
This unit is able to store up to 50 sets of measurement data in memory, thus making it possible to output large
batches of data all at one time.
● PC connectivity
The connection of a PC and the use of the data logger, “FDL-02” (option) allows the drying state during
measurement, nal measurements, graphs, and the like to be displayed on the PC.
● Printer port
The connection of the printer (option) allows the drying state during measurement, nal measurements, and the
like to be printed out.
● Stainless-steel sample dish with 10 mm in diameter
● Scale calibration
■ Measurable objects
● Materials from which only water evaporates by heating
● Materials for which no dangerous chemical reactions or other changes occur as a result of
heating
* Measurements can be performed using virtually any material meeting these conditions.
