With so many products on offer, it was very difficult to select just a few to highlight.


By downloading the Hanna Lab App and choosing the right electrode for the testing medium, your smart phone or tablet becomes a professional grade pH meter in seconds, utilising Bluetooth® 4 low power technology which allows transmission of pH and temperature data to your device. The HALO™ is also compatible with the Hanna Edge® Blu meter.

Whatever the application – from small businesses and hobbyists to research grade laboratories – Hanna HALO™ is designed to deliver high quality pH and temperature results quickly and consistently.

Features include up to five-point pH calibration with seven standard pH buffers available; calibration reminder; pH and temperature updated every second; basic and full GLP; fluid, dynamic graphing; measurement alarms alerts you if the measurement threshold is exceeded; one button sample tagging; data-logging with custom annotations; data share via email in CSV format plus help and tutorials.

Edge® Meters

Edge® is the latest innovation from Hanna Instruments, offering the most advanced technology. With Edge®, the measurement of pH is simpler, quicker and more accurate than ever before. Combining high precision technology with the user-friendly dimensions and format of a small digital tablet, Edge® is breaking new ground in electrochemistry. Cutting-edge design, capacitive touch screen and an intuitive user interface are just a few of the great attributes that make Edge® stand out as the most innovative bench meter on the market.

Edge® measures pH through its unique digital electrodes. Connected via an easy plug-in 3.5mm connector, these smart electrodes enable Edge® to automatically recognise and store sensor type, ID and calibration information. Edge® even warns users if the electrode is dirty or if buffers are contaminated during calibration using the exclusive HANNA CAL-CHECK feature. Advancing this technology even further, Edge® will also warn you if the electrode bulb is cracked or if the junction is compromised.

The Edge®blu pH meter uses Bluetooth® Smart technology (low energy) for outstanding battery life and allows the connection of any of the 10 variants of the HALO™ pH electrodes.
