LabStart-aw
Mobile, accurate, reliable and low cost
A good start is essential for every project and undertaking. That is why
the LabStart-aw has been developed to introduce quality managers,
production personnel and laboratory technicians to water activity
measurement. This instrument is simple- to- operate, providing basic
measurement functions, yet still having built-in automatic equilibrium
detection and the well-proven resistive-electrolytic sensor technology
as employed in all Novasina water activity meters. As standard, the
LabStart-aw is supplied with one re-useable humidity calibration
standard which provides a very economical solution to precision water
activity measurements in one simple kit. Furthermore, the calibration
standard is an easy method for verification of the instrument’s high
performance.
