A&D MC-A/MC-M Series

Mass Comparators (Precision Balances with Extended Readability)

Enhanced Performance. Unchanged Value.

The A&D MC-A and MC-M series mass comparators are precision balances with extended readability, built for high-precision and automated weighing. Auto-centering pans correct eccentricity errors, an extra decimal place tracks small weight changes even under heavy tare weights, and Impact Shock Detection (ISD) alerts and logs high-impact events.

Four models cover capacities from 1100 g to 32.2 kg with readability from 0.0001 g to 0.01 g. The MC-A series features easy-to-adjust leveling feet with thumbwheels, while the MC-M series is IP65 dust and waterproof.

*Under good environmental conditions using the auto-centering pan, or with consistent positioning in automated systems.

  • Auto-centering pans available for consistent accuracy through automatic correction of eccentricity errors
  • Extra decimal place enabling accurate tracking of small weight changes in automated systems with heavy tare weights
  • Impact Shock Detection (ISD) for reliable automation with alerts and logging of high-impact events
  • Cushioning under the weighing pan to mitigate impact shocks significantly
  • Tare memory function that saves the tare value in non-volatile memory
  • AD-Just – Automatic self-sensitivity adjustment using the internal weight
  • Minimum weight setting and alert functions
  • Selectable response characteristics for trading weighing speed for higher display stability or vice versa
  • User access control (UAC) that password-protects the balance from misuse
  • GLP/GMP/GCP/ISO compliant output to meet documentation requirements
  • Universal Flexi Coms (UFC) to customize printout content and layout*1
  • Gross/Net/Tare output
  • Data memory function to save weighing results, calibration results and unit masses to be used in counting mode in the device itself
  • Counting mode with the Automatic Counting Accuracy Improvement (ACAI) function
  • Percent mode function for target weighing or checking sample variation
  • Animal weighing (average & hold) function for weighing moving objects
  • Statistical calculation function (SCF) to facilitate the analysis of measurements
  • Five-level comparator function with buzzer
  • Auto power ON and OFF functions
  • Underhook for weighing a magnetic material as well as measuring density
  • Easy-to-adjust leveling feet with thumbwheels (MC-A)
  • IP65 dust and waterproof (MC-M)
