Grab and go
Designed for government inspectors and third-party auditors, the battery-operated portable PAWKIT water activity meter 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.
Portable water activity
The 3.5 x 4 inch PAWKIT weighs just 4 ounces and is designed to fit in a lab coat pocket. It runs on two coin cell batteries that last up to 3 years under normal use. It has an easy two-point calibration using AQUALAB standards.
The PAWKIT is designed to make readings where a bench top meter is not practical. Its small size and battery power deliver the ultimate in portability, but limit the PAWKIT’s accuracy (± 0.02 aw) due to its capacitance sensor and lack of temperature control .
The PAWKIT portable water activity meter should only be used in situations where a higher accuracy reading is not critical to ensure or document safety and quality.

In addition to the standard dew point sensor, the Series 4TEV has a hygroscopic polymer capacitance sensor that can be used to measure the water activity of samples containing volatiles. You can switch between sensors using the instrument menu. The capacitance sensor is less accurate (± 0.015 aw) than the dew point sensor (± 0.003 aw).
