DESCRIPTION
The Ohaus Precision Standard series balances are precision weighing instruments,
designed to provide years of service with virtually no maintenance. The Precision
Standard series is constructed using a die-cast aluminum base finished with a durable
epoxy powder paint which is resistant to commonly used acids, contains a one piece
solid-state precision electronics PC board, a seven digit LCD display which is 0.6 inches
in height. All Precision Standard series balances are factory set to measure in grams.
Each balance operates through a series of menus which enable precise calibration and
linearity along with various other parameters which enhances operation. A built in lock
switch prevents preset settings from being changed. To prevent measurements from
being affected by air currents, a draft shield is used on Models JR120, JR200 and
JR400D balances. Power is supplied through an AC adapter which is available in five
voltages for world-wide usage. Accessories include: an RS232 interface kit which
allows printing of results through an external computer, an RS232 Interface cable with
a print switch, weigh below hook, security device and calibration weights.
