Water activity meter - Aqualab Series 4TE Duo
Water activity and moisture content measurement in 5 minutes or less.
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.
- 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
