POrtable WATER ACTIVITY METER
PAWKIT
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.
Limitations
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.
