AQUALAB PAWKIT

  • Description

    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.
