Applications Weighing: Determines the weight of the items on the pan in the selected unit of measure. Piece Counting: Count the number of pieces on the pan using a uniform weight. Percent Weighing: Measures the weight of a sample displayed as a percentage of a pre-set reference weight. Check Weighing: Compares the weight of a sample against target limits. Dynamic Weighing: Weigh an unstable sample load. The balance takes an average of weights over a period of time. Totalization: Measures the cumulative weight of multiple items. Cumulative total may exceed balance capacity. Density Determination: Determines the density of solids or liquids. With the integrated weigh below hook, specific gravity tests can be performed for items that cannot easily be placed on the weighing pan. Display Hold: Manually holds the last stable weight or the first highest stable weight value on the display. Mole Weighing: Measures the weight of a sample and automatically calculates it into the mole. MODELS AVAILABLE: Applications Weighing, Parts Counting, Percent Weighing, Check Weighing, Animal/Dynamic Weighing, Totalization, Density Determination, Display Hold, Molar Weighing Display 4.3' (109mm) touchscreen display with color VGA graphics resolution and user controllable brightness Operation Power supply (adapter supplied) or batteries (not supplied) with low battery level indicator and programmable automatic shutdown Communication RS232, USB host, USB device, Ethernet or Bluetooth® (available as accessories) Framework ABS housing, stainless steel pan, ABS draft shield (1 mg models only), weigh below hook, transport lock, manual calibration lock switch, security slot, stabilizing feet, level indicator illuminated front Construction features Stability indicator, stackable design with included storage cover (except 1mg models), mechanical and software overload and underload protection, battery life indicator, auto power off, auto tare, calibration weight provided in models with capacity greater than 620 gr.
