  • Space Saving:  A careful redesign of our weigh cell assemblies has allowed us to pack more technology into a compact, 8 x 15 inch footprint.
  • Convenient Connectivity: Optional thermal printer or USB flash drive can be used for result documentation.
  • Semi Micro Class (W3002A-120):  Readability of 0.00001 g up to 62 g, and 0.0001 g up to 120 g.

Accuris™ Series DX Analytical Balance

  • Upgraded Weighing Performance:  Electromagnetic Force Restoration (EFR) technology, fast response and stabilization, and automatic internal calibration.
  • Refined Control Panel: Enhanced graphical interfaces significantly improve ease of use.
  • Space Saving:  A careful redesign of our weigh cell assemblies has allowed us to pack more technology into a compact, 8 x 15 inch footprint.

Accuris™ Classic Analytical Balance

  • Readability to 0.0001 g (0.1 mg).
  • Available with Quick-Cal™ internal calibration feature.
  • RS232 port for data output to a computer or printer.
  • Multiple mode options (standard weighing, count mode, & percent).
 
 
Accuris Compact Balance Series, Readability, 0.1 to 0.01 g

Accuris™ Compact balances have been designed to meet the basic needs of academic and research labs requiring weight determinations to increments of 0.01 g to 0.1 g. Their reliable and precise weighing technology utilizes gold-plated, ceramic capacitors to determine sample mass. 

  • Compact housing: 7.5 x 11 inch footprint
  • Readability 0.1 to 0.01 g
  • Easy in-lab calibration feature
  • RS232 port for data output to a computer or printer
  • Multiple mode options (standard weighing, count mode, & percent)
  • Simple, reliable performance

Accuris™ Compact balances have been designed to meet the basic needs of academic and research labs requiring weight determinations to increments of 0.01g to 0.1 g. Their reliable and precise weighing technology utilizes gold-plated, ceramic capacitors to determine sample mass.


The Compact line includes 6 models covering a wide range of maximum weight capacities. The lower capacity units (120 g, 300 g, and 500 g) are readable to 0.01 g, and come with a draft shield ring to prevent air currents from affecting measurements. These models feature a 4.5-inch diameter, stainless steel weigh pan.  The larger capacity models (1000 g, 5000 g, and 10,000 g) do not include the draft shield ring, come with larger weighing pans of 6.3 to 7-inch diameter, and are readable to 0.1 g.


All balances in the Accuris
™ Compact line offer large, brightly lit LCD panels, and are easy to operate using the intuitive and splash-resistant control panel.  Different modes allow weight to be displayed in various units: grams, ounces, carats, and simple programs can be used for piece counting and percent deviation weighing.


Leveling feet are located toward the front of the balance for easy access, and a leveling bubble in the control panel is easy to see for quick and simple leveling on the lab bench. The balances can be calibrated using a calibration weight and a few keystrokes on the control panel - just select a calibration point in the calibration mode, place the calibration weight onto the weighing pan, and press the "CAL" button.


Lightweight, and small in size, Accuris™ Compact balances will provide years of trouble-free service.
