Hanna Instruments

Hanna Instruments was founded in Padova, Italy in 1978 by Anna and Oscar Nardo and is currently headquartered in Woonsocket, Rhode Island. It’s presently headed by their children, Pamela and Martino Nardo. With over 60 offices in 43 countries worldwide, Hanna continues to grow to meet the demand for its products in a variety of industries. Over the years, Hanna has been at the forefront of technology and innovation.

The philosophy of the Nardo family has always been to be able to supply customers around the world with practical, cost-effective solutions for their testing needs. When Hanna introduced the pHep® pH (pH Electronic Paper) tester in 1986 it literally revolutionized the world of testing. Millions of people from various industries were now capable of testing pH simply, accurately and affordability. This is the basis for the winning philosophy strongly embedded in Hanna. When we introduced the world’s first single parameter series of automatic titrators dedicated to food analysis in 2005, we put thousands of users from around the world in the position to improve the quality of their product by performing their own in-house analytical tests. The driving philosophy that has been a Hanna trademark for over three decades has enabled us to provide the right instrumentation to our customers with world class service and support.

We believe in controlling the quality of our products from their inception to delivery. For this reason, we manufacture all of the products we bring to market. To ensure consistency and quality, each of our manufacturing facilities are specialized in a product family. To stay at the forefront of quality and innovation, we continuously invest in new technologies and equipment as well as implementing new manufacturing techniques. As a vertically integrated manufacturer, Hanna does not subcontract any part of manufacturing. Processes such as plastic molding, glass blowing, chemical bottling and assembly are performed in one of our state of the art facilities. Hanna is an ISO 9001:2000 certified company.

Perpetual Innovation

For over thirty-seven years, Hanna has prided itself in being a world leader in innovation of analytical instrumentation. Headed by our team at the home office, Hanna’s research and development department constantly challenge themselves to invent new testing techniques and to advance existing technology. The minds at Hanna work to achieve the common goal of simplifying analytical testing through improving instrumentation, sensor development, reagents and chemicals.

In 1985, Hanna was first to introduce a pH electrode with a built in temperature sensor. This electrode soon became commonly used throughout the worldwide market. In 1990, after listening to its customers, Hanna was one of the first companies to launch a line of waterproof, portable instruments built specifically for harsh environments. The concept of giving users the possibility to check the accuracy of their digital thermometer (CAL Check™) was introduced by Hanna in 1995 and is still unique today. With technology that was first introduced by Hanna in 2000, the HI98129 and HI98130 Combo testers allowed simultaneous testing for pH and EC in a single instrument. In 2004, Hanna introduced HI98121, the worlds first combination pH and ORP tester. In late 2013, Hanna introduced edge®, a 3-in-1 benchtop/ portable/wall-mount pH/EC/DO meter with a 5.5” screen, thickness of 1/2” and weight of under 9 ounces. In 2014, Hanna launched HALO™, the world’s first pH electrode with Bluetooth® Smart technology and the companion Hanna Lab App.
