AQUALAB’s smallest water activity (aw) meter. Designed for the field, not for the lab.
You need a reading on-site, without access to a bench or power source. You are verifying a spec, not setting one. Portability is the primary requirement.
If you are running daily R&D, Production, or QA checks, the accuracy limits of the PAWKIT will cost you. Yield, moisture targets, and product quality are directly tied to how precise your meter is.
Within the portable aw meter category, nothing matches what the PAWKIT delivers; the accuracy it achieves at its size, the simplicity of use, and the support that comes with it.
Every PAWKIT comes with the same calibration standards, service options, and applications support as any AQUALAB benchtop. When you need help, the same team is behind it.
±0.02 aw is the tightest specification available in a battery-powered portable meter.
Calibration standards, service contracts, and direct access to our team of moisture experts, same as any benchtop.
Moving between the PAWKIT and AQUALAB benchtops doesn't require retraining, the workflow carries over. When your volume grows and precision starts to matter more, moving to a benchtop is straightforward.
The 4TE is built around the variables that matter most in production and R&D environments; temperature stability, a sealed measurement chamber, and precision tight enough that you can hit your spec without over-drying.
Measure closer to your actual target and ship product at the right water activity.
Every reading reflects the sample itself. Facility conditions, ambient humidity, and room temperature stay out of the equation.
Results are consistent run to run, regardless of where in your facility you measure or what time of day you pull the sample.
High throughput with results in under five minutes, built for production environments where throughput cannot be a bottleneck.
