Aquarium Water testers from Hanna.

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.

Today, Hanna manufactures over 3,000 products in production facilities located in USA, Romania, Italy and Mauritius. We are proud to offer unique solutions for our customers. We continue to strive to understand the challenges that our customers are faced with in performing analytical measurements so that we can develop a solution that will provide a simplified and accurate way to measure.
