DESCRIPTIONDESCRIPTION
DESCRIPTION
The Ohaus Precision Advanced GT Series balances are precision weighing instru-
ments, designed to be versatile, accurate, easy to operate and will provide years of
service with virtually no maintenance. The Precision Advanced series is constructed
using a die-cast aluminum base finished with a durable corrosion resistant epoxy
powderpaint. Itcontainssolid-stateprecisionelectronicsPC boards, andasevenand
a half, 0.45 inch digit, Vacuum Fluorescent display. Each balance operates through
a series of menus which enhances operation. A built in lockswitch prevents preset
settings from being changed.
FEATURES
Precision Advanced balances contain four main display menus which enable you to
calibrate and configure the balance for specific operating requirements.
