• Water activity meter

Water activity meter

  • Full temperature-control ( 0-60°C ) for highest accuracy
  • Reusable SAL-T calibration standards
  • Automatic recognition by RFID-tag

Second to none water activity meter with cutting-edge technology, perfect for daily routine determination of water activity in QC-labs in food and pharma.

This meter is as well very suitable to support further investigation to find the source of product spoilage, texture failures or rancidity.

Our cutting-edge and unique sensor technology for water activity measurement, supported by a full temperature-controlled measurement chamber, provides the pre-requisite for best accuracy and reproducability.

Advantages

  • Full temperature-control ( 0-60°C ) for highest accuracy
  • complete 21CFR11 conformity thanks complaint user management and audit trail
  • Various measuring modes including fast mode
  • Reusable SAL-T calibration standards with automatic recognition by RFID-tag
  • Automatic equilibrium detection to ensure best repeatability and comparability of measurement values


Fast and Accurate

Outstanding meter for hassle-free water activity measurement and result documentation, including 21CFR11 compliant audit trail and user management, automatic verification or calibration, contactless salt standard identification by RFID and a quick mode which guarantees a completed measurement within 10 mins. Additional features like full temperature control in the range of 0-60°C, measurement range of 0.0300-1.0000 aw and a much easier handling of chemical protection filters due to magnetic fixing completes the LabMaster-aw neo. Still compliant with all standards like AOAC, ISO, USP and others
