laboratories. This scale provides positive poise positioning, notched and tiered beams, and
is magnetically damped to slow oscillation. Agate bearings, steel knife edges, and stainless
steel pans ensure resistance to rugged handling. This model contains a platform recessed
in the base, which can be raised for specific gravity determinations.

Pioneer OHAUS®
Balance
Designed for basic routine
weighing in laboratory and education
applications. The Pioneer
analytical-style draft shield is
designed with all glass panels,
including three sliding doors. All
doors including the front and back
panels, are easy to remove and replace, and
together with a stainless steel bottom, make
it fast and easy to clean. Should breakage occur,
within three easy steps, each replacement door and
panel can be installed in seconds. Features an up-front level indicator, eliminating the
need to look behind the balance during the leveling process. A quick glance at the upfront
level indicator helps to ensure the balance is level prior to use. Three filter modes
and adjustable zero tracking are ideal for working in slow filling applications where sensitivity
is a must. When working in harsh environments, user can adjust balance settings
to compensate for vibrations and other disturbances. Features RS232, calibration lockout,
security loop in rear, weight below hook, A/C adapter, in-use cover, secondary display
with backlight, density determination kit, calibration masses, security device-cable and
lock type, printer, PC and printer cables, and communication software.
