1. Introduction
Thank you for choosing the Shimadzu Electronic Moisture Balance MOC-120H. MOC-120H has high
reliability by employing the UniBloc cell, introduced for use in electronic balances by Shimadzu in 1989.
It provides WindowsDirect functions for transfer of measurement results to personal computer without
installing software. This and other various functions can be used to meet the operator's objectives.
In order to make full use of the functions and performance provided in the MOC-120H, please read this
instruction manual before using the balance and keep the manual for future reference.
For information on the following points, please contact your Shimadzu Balance representative.

2. Description 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*1cell which provides excellent responsiveness,
temperature characteristics, and shock resistance. This UniBloc*1sensor ensures excellent reliability in moisture
content measurements over a long period of use.
New Auto Taring Function
The MOC-120H 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-infrared quartz heating lamp (with a central wavelength of 2.6 +m). 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 drying conditions.
What‘s more, this heating lamp also provides a long service life 5 to 10 times greater (20,000 to 30,000 hours) than
older infrared or halogen lamps.
A wide selection of measuring modes
The MOC-120H provides a wide selection of measuring modes (automatic operation mode, timed operation mode, high-
speed drying mode, low-speed drying mode, stepped drying mode, and predictive measuring mode) which makes it
possible to perform measurements under the best drying condition for each sample.
The ability to store measuring conditions
The MOC-120H provides 10 measuring conditions storage areas which may be used to store sets of measuring
conditions to be used for different types of samples, thus reducing the work of programming settings before each
measurement.
Data memory
The MOC-120H is able to store up to 100 pieces of measurement data in memory, making it possible to output large
batches of data all at one time.
Printer port
The MOC-120H is equipped with a printer port which may be used to connect to the optional printer, thus making it
possible to print out text or graph data showing final measurements or intermediate drying states while performing
measurements.
The ability to display changes in moisture content (6M) in a numeric and bar graph display
The change 6M in moisture content over 30-second intervals is displayed in a numeric and bar graph display, thus
making it easier to estimate when a measurement should be completed. This feature is also useful in helping to
determine measurement completion conditions.
2-3 Applications (i.e., materials which can be measured)
Materials for which water is the only or main component which evaporates as a result of
heating
Materials for which no dangerous chemical reactions or other changes occur as a result of
heating
* Measurements can be performed with virtually any material meeting these conditions.
