Legacy AQUALAB Pawkit Water Activity Meter
Grab and go
Designed for government inspectors and third-party auditors, the lightweight Pawkit is perfect for water activity spot checks on the go.
How it works
To make a measurement, flip back the sensor cover and fit the Pawkit over a standard AQUALAB sample cup. Push the button for a water activity reading in 5 minutes.
With a limited ± 0.02 aw accuracy, the Pawkit should only be used to verify readings or where a higher accuracy reading is not critical.

The AQUALAB's 4TE’s dew point sensor doesn’t take a “quick mode” reading or approximate water activity. It actually measures water activity with 0.003 accuracy in about 5 minutes.
