Our 5th generation desktop series is available in single and multi-parameter models with or without Bluetooth connectivity. The AB603 is a single-parameter Bluetooth desktop pH / ORP / temperature meter that connects to an iOS tablet to provide the same user experience as users' favorite apps while providing graphing, guided calibration routines, data storage according to GLP, data sharing, cloud storage and user-defined compliance policies.

Known accuracy and repeatability
Repeatable and accurate results achieved with NIST or US buffer calibration up to 5 points for pH, 1 point ORP offset calibration.

Great user experience
The sleek and modern design is combined with a large, high-contrast backlit LCD display, tactile and audible feedback buttons, and a separate electrode holder.

Improved electrode maintenance and low cost of ownership
Standard BNC connector for pH or ORP electrodes and temperature electrodes.

Improved application performance
The free iOS app is as easy and convenient to use as the user's favorite app, and gives you complete control over all instrument functions, calibration routines and more.

Easily share data locally or in the cloud
Share saved data with other applications such as Notes and Evernote, or cloud services such as Google Docs.

High availability of information
Display of pH and ORP with temperature readings along with electrode efficiency, last calibration date and real-time graph.

GLP Compliant Data Warehouse
More than 10 thousand pH or conductivity and temperature datasets, and calibration data such as calibration date, buffers used, calibration slopes and calibration offsets.
