Teaching pH in a university laboratory

The Hanna Lab App turns an iPad into a full-featured pH meter at a pocket pH meter price.The concept of pH is taught to students at an early age. Starting in grade school, substances are classified as acids, bases, or neutral; continuing through secondary school and university, pH and related concepts are taught more in depth. pH is a critical parameter in a multitude of industries, including food and beverage, pharmaceutical, wine, plating, textiles, water treatment, and more. Many graduating students, especially those with a focus on science, will need to measure pH in the course of their professional careers. Therefore, an understanding of the theory of pH, how to correctly measure pH, and how to maintain and troubleshoot a pH meter and electrode are invaluable skills for graduates to have.

A university contacted Hanna Instruments looking to purchase affordable, easy to use pH meters for their introductory chemistry class. Each laboratory class had 15 to 20 students enrolled, and as part of the class curriculum the professor wanted to ensure that the students learned how to properly use a pH meter. Due to budget restrictions, the professor was initially considering one research grade meter for their research projects and seven to ten inexpensive pocket meters. However, during a follow-up phone call, the Hanna sales representative learned that the professor had access to five iPads for use in their classroom and teaching laboratory.

Hanna recommended the HI11312 HALO™ pH Electrode with Bluetooth® Smart Technology. The HI11312 HALO is a glass body electrode that transmits data wirelessly to an iPad® that is running Hanna Lab App.

The Hanna Lab App turns an iPad into a full-featured pH meter, with functions including calibration up to five points, choice of standard or custom calibration buffers, continuous data logging and graphing, and data transfer. The professor was thrilled that the HI11312 HALO in conjunction with the Hanna Lab App and iPad offered research grade functionality at a pocket pH meter price, providing affordable equipment for their laboratory class.
