Hanna Milestones

Hanna is Technology and Innovation For over thirty-five 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 newtesting 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.

1980 World’s first single-probe portable conductivity meter The HI8033 is a four pole conductivity portable meter. Having a four pole design allowed the meter to measure a variety of different solutions with different conductivity values. The same meter can be used to measure both deionized water and fertilizer solution.

1978 Hanna Opens in Italy

Hanna was founded in Limena, Italy. Limena is a province of Padua (AKA Padova) and is located in Northern Italy. It is approximately 40 km west of Venice. Padua is well known for the University of Padua. Many great scholars of our time have spent time at the university. Most notable scholars include Galileo Galilei and Nicolaus Copernicus.

Introduction vi about Hanna

1982 World’s first pH controlled chemical dosing pump The DP7916 combined a pH meter with a chemical dosing pump in order to maintain a desired set point of a process applications. The BL7916 is the second-generation design and is still widely used by many customers including plating, wastewater treatment, water treatment and swimming pools. 1984 World’s first microprocessor-based hand held pH meter The HI8424 was the first portable microprocessor pH meter. The microprocessor allowed for automatic calibration as compared to manual calibration with trimmers or potentiometers. The calibration information was stored in the meter even when it was powered off.

1985 World’s first pH electrode with built-in temperature sensor

The HI8414 pH meter was the first meter to use a pH electrode (HI1213S) with a built in temperature sensor. The temperature sensor allowed for the automatic correction for changes in pHwith changes in temperature as calculated by the Nernst equation. This advancement is now commonplace in the industry.
