In 1978 Hanna Instruments was founded in Limena, Italy by Oscar and Anna Nardo. Since that time, Hanna Instruments has
grown to be a worldwide leader in the development of electro-analytical instrumentation. The development of novel
instrumentation for customers that would not have normally used instrumentation is what has led to the success of the company.
In the 80’s the company had a mission to provide a pH meter that was affordable, accurate and easy to use. The result was
the pHep (pH electronic paper). This meter used an integrated circuit to measure the voltage response of a pH electrode
packaged into a pocket-sized meter. The calibration of the meter was performed manually and the price was less than $50.00. Having a simple operation and very affordable price point brought the advantages of an electro-analytical measurement of pH to the masses. Whether it be a farmer looking to measure the pH of soil to the printing press operator that needs to measure the pH of a fountain solution. Hanna Instruments provided the user with an accurate electronic alternative to litmus paper and chemical indicators.
Hanna Instruments has a history of developing innovative products that make analytical measurements easier to perform at
an affordable price. Many innovations introduced by Hanna are now the norm for the instrumentation industry.
