Precision Instruments for Water Activity Measurement

For over 50 years Novasina is the leader in the production of precision instruments for water activity measurement in foodstuff,

processed food as well as pharmaceutical, chemical products and cosmetics.

Thanks to a longstanding experience and research and development we are able to offer today reliable, high quality ‘Swiss made’

products that set new standards in the water activity measurement.

Novasina offers three types of water activity meters, carefully developed and designed:

• LabSwift: portable aw-meter without any temperature control, thus environmental (lab) temperature is the measurement temperature. Suitable for low to medium aw-measurement ranges
• LabTouch: Semi-temperature controlled measurement chamber, optimised for the measurement of aw values in the range of 0.6aw - 0.90aw
• LabMaster: High-end instrument with full temperature-controlled chamber. It can handle all types of samples from 0.04aw to 1.00aw.

Why different models?

Because every sample has its own characteristics in terms of ingredients, texture, colour and taste and thereby influences

the free water and finally the water activity in a different way. This factor plus the temperature influence defines the

measurement time and the accuracy of the same. Stable measurement conditions are finally the key to a successful

quality control! As a consequence, three different models are required being capable to always offer the most suitable

solution to customers samples and requirements.
