Casing construction, strong protection against dust and moisture.
Multiple weighing units with most of the common units used around the world.
Standard RS-232C serial interface to communicate with a computer and to output the Good
Laboratory Practice (GLP) / Good Manufacturing Practice (GMP) compliant report.
Statistical calculation mode to statistically calculate the weight data, and display or output the
sum, maximum, minimum, range (maximum-minimum), average, standard deviation and
coefficient of variation.
Comparator Indicators, displaying the comparison results.
Hold Function, provided for weighing a moving object such as an animal.
Breeze break, provided for better stability if drafts are present.
Underhook, provided for suspended weighing.
As options, the USB interface (HRA-02), the Ethernet interface (HRA-08) and the built-in
battery unit (HRA-09) are available.
Connecting the USB interface, by cable to a Windows computer, allows transmission of the weight
data to Excel or Word. The Ethernet interface allows connection of the balance to a personal
computer through a LAN. The battery unit allows use of the balance where a power source is not
available.
The AD-8920A remote display, that is sold separately, allows reading the weight value in a
place away from the balance.
The optional AD-1688 data logger provides easy weighing data management.
●
The optional AD-1687 weighing environment logger provides easy management of the
weighing data, such as environmental data for the weighing and so on.
