Where it all began...

It all started in 1978 in Italy, where our founders, Oscar and Anna Nardo, set out to make science testing accessible to everyone! Fast forward to today, Hanna Instruments is now led by Martino Nardo and Pamela Nardo, son and daughter of our founders. We strive to create testing equipment that is easy-to-use, accurate, and readily available. 

We value our customers and work with you every step of the way to ensure your testing success.
This is our driving force, it's who we are.

Aqua-Hydro feild Lab

We make a wide array of testing equipment for various industries and applications.




We create our products from design to completion

At Hanna, we take pride in every single product that we build. From an original idea scribbled on a piece of paper in a notebook to a finished, final product that is boxed and ready for testing, we oversee every aspect of the manufacturing process. It is this level of attention to detail that sets us apart.



We really know our products inside and out

From our engineers making the circuits and firmware for our meters to our glass blowers handcrafting our pH & ORP electrodes, all the way to the final production stages, where our quality team checks each piece of testing equipment before it is delivered to your doorstep, yes, we do it all.
