Many of our small, fast-growing customers prefer the SKALA-connected AQ1 over the Pawkit. The AQ1 lets you manage costs and manage compliance.

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.

Looking for a full-featured benchtop?

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.
