Halo Gel Filled Bluetooth pH Electrode

This Bluetooth® enabled electrode turns your Apple or Android device into a full-featured portable pH meter. HALO gives you the ability to measure, chart, record and share your data right from your phone.

HALO enables the gardener to automate their pH and temperature logging efforts. This helps keep gardeners accountable and focused. You can stop relying on hand written data logs when you start using the HALO. pH and temperature readings are time and date stamped. Simply look back over the recorded history and find the data you need.

HALO pH electrodes can connect with any Apple or Android device running the Hanna Lab App. The Hanna Lab App can be downloaded for free by visiting the Apple App Store or Google Play stores. A demonstration can be had by downloading the Hanna Lab App, no purchase is necessary.
