SKALA-Connected AQ2

Smart water activity meter

AQUALAB speed and accuracy. SKALA Lab connections.

SKALA-Connected AQ2

Speed and accuracy get smart

The AQ2 is our first fully connected chilled mirror dew point water activity meter. It pairs the legendary speed and accuracy of an AQUALAB water activity meter with SKALA’s power to automatically collect your data and manage all the compliance details.

Chilled mirror. Stone cold precision.

Accuracy: +/- 0.005 aw. Speed: less than 5 minutes.

What makes the AQ2 so fast and accurate?

Unlike capacitance sensors, the dew point sensor is a primary measure of water activity. It actually measures water activity, not a secondary parameter correlated with water activity. So you get the accuracy you need and speed you can count on.

Dump downtime

The AQ2 water activity meter is designed with layers of reliability. It monitors itself and notifies METER support when something doesn’t look right. Your subscription plan includes proactive service: we call you before there’s a serious problem.

And the AQ2’s measurement electronics are contained in a factory-calibrated aluminum block. Each AQ2 is delivered with a fully calibrated backup block, so you’re never more than 5 minutes away from a fully factory calibrated instrument. No shipping delays, loaner instruments, or repair wait times.

Plus, your subscription includes full membership in the annual block exchange program, with service plan and extended warranty.

Power up with SKALA Lab

The AQ2 is for QA labs that want to invest in the power and savings that come from connected instruments and automatically collected data.

The first year’s subscription is free, and includes access to SKALA Lab plus membership in the block exchange program with service plan and extended warranty, proactive service monitoring, and data storage for all the instruments you connect through the Hub.

Make the right connections

Every AQ2 comes with SKALA Hub and includes six open USB ports. Connect up to six additional instruments—AQ2s, existing AQUALAB instruments, even non-METER instruments—pH meters, refractometers, scales, etc. SKALA Lab will collect the data automatically. No writing, no typing, no data entry. If the instrument is not in SKALA’s device library, our team will profile the device and connect it to the system*.
