Aqualab Series 4TE - Fastest most accurate water activity meter

The AquaLab Series 4TE water activity meter has internal temperature control which allows you to choose a measuring temperature between 15 and 50°C. Since water activity is temperature dependent, the AquaLab Series 4TE will allow you to expertly manage the internal temperature to precisely measure the water activity of your product. The AquaLab series 4 can be used in:

  • Accelerated shelf-life studies
  • Isotherm studies
  • Studies determining the effects of temperature on a sample aw
  • Evaluate the effects on a sample when there are large fluctuations in ambient temperature
  • Meeting government or company regulations on temperature specific aw measurements

•0.0001 aw resolution

•Ability to restrict user access and to control which instrument settings can be changed by users

•Displays water activity and moisture content simultaneously**

•Data storage (stores up to 16000 readings for later download)

•New 'flip-top' block gives easy cleaning access

•Improved sample chamber seal

•Advanced software reporting package
