The METER AquaLab "PRE" is a robust entry-level water activity meter.
It uses the same industry-standard primary water activity method you find in our top-of-the-line AquaLab Series 4TE.
The Pre may look basic, but that’s because all the good stuff is inside!
Accurate — ±0.01 aw
Verifiable — with independent salt standards.
Repeatable — different users, different locations, same result.
Easy to use — precise measurements with minimal training.
