MICRO-ANALYTICAL BALANCE, A & D
Micro analytical balances, with a built-in fan-less ioniser in a neutralising chamber,
designed to eliminate the problem of static electricity, even on fine powders,
allowing a high accuracy of measurement. The discharge electrode pins of the
ionizer can be used continuously for approximately 10,000 hours and are safely
replaceable. The thin evaporated metal coating of the windshield blocks outside
static electricity.
Features include automatic self-calibration with a motor-driven internal calibration
mass, automatic response adjustment, 2 special pans for weighing particulate
matter filters, a double-ring structure around the weighing pan and two vertical
shield under the separation plate (C12-1900 & C12-1905 only), a removable
separation plate between the neutralising and weighing chambers makes room for
tall beakers and flasks, clear, white backlit LCD display, inter-lockable slide doors,
built-in environmental sensors, 12 units of weighing (including counting and %
mode) and data memory function. The two standard interfaces, RS232C and quick
USB, allow for 2 different devices (e.g. PC and remote controller or printer) to be
connected to the balance simultaneously. An external key plug allows an optional
foot switch to be attached. C12-1900
Supplied complete with AC adapter, Instruction manual, WinCT (CD-ROM), Weighing
data logger (C12-3680), tweezers for calibration mass, tweezers and two weighing
pans for PM filters (C12-1900 & C12-1905 only).
