Basic characteristic:

  • night,working and service regime
  • ergonomic approach and visibility for weighing operation
  • sides and doors of working spaces are made from acrylic glass; case for pre filter and extraction unit are made up from steel covered with plastic
  • adjustable extraction air speed on working aparture is: 0,2÷0,7 m/s
  • integrated working basis for weigh from monolithic granite sheet, thick: 4 cm for precise weighing: ≤ 1 x 10 - 4 g
  • integrated low noise fan
  • automated manipulation with default working regimes, alarms for nonconforming conditions and failures

Protection for operator, environment and weighing process:

  • Extraction air speed prevents particles emission from weighing space through working hole toward operator.
  • For vibration protection, extraction unit is placed away for stable stand with weighing base and with extraction-protected unit is connected with flexible tube.
  • 1. Degree filtration is integrated in extraction chamber while 2.degree is integrated in fan-filter module which eject totally extracted and filtered air without danger for environment

Installation options on customer demand:

  • Installation with stabile stand, 750 mm working height for weighing
  • Variant for placement on existing customer table
